• Add --mode flag for CLI output control (text/json/rpc)

  - text mode: only outputs final assistant message text (default)
  - json mode: streams all events as JSON (same as session manager writes)
  - rpc mode: JSON output + listens for JSON input on stdin for headless operation
  - Suppress informational messages in json/rpc modes

• Add proper truncation notices and comprehensive tests for read tool

  **Improved output messages:**
  1. File fits within limits: Just outputs content (no notices)
  2. Lines get truncated: Shows "Some lines were truncated to 2000 characters for display"
  3. File doesn't fit limit: Shows "N more lines not shown. Use offset=X to continue reading"
  4. Offset beyond file: Shows "Error: Offset X is beyond end of file (N lines total)"
  5. Both truncations: Combines both notices with ". " separator
  
  **Comprehensive test coverage:**
  - Files within limits (no notices)
  - Large files (line truncation)
  - Long lines (character truncation)
  - Offset parameter
  - Limit parameter
  - Offset + limit together
  - Invalid offset (out of bounds)
  - Combined truncations (both notices)
  
  All 17 tests passing ✓

• Add line limits and truncation to read tool

  - Default limit of 2000 lines per read
  - Maximum line length of 2000 characters (truncates longer lines)
  - Add optional offset and limit parameters for pagination
  - Show truncation notice with instruction to continue reading
  - Plain text output (no line numbers)
  
  Examples:
  - `read path/to/file` - reads first 2000 lines
  - `read path/to/file offset=2001` - continues from line 2001
  - `read path/to/file limit=100` - reads only 100 lines
  
  This prevents extremely large files from overwhelming context.

• Match export output style to thinking level display

  Changed export success/error messages to match the style used for thinking level changes:
  - Use Spacer(1) instead of empty Text for proper blank line spacing
  - Use chalk.dim() for success message instead of chalk.green()
  - Add left padding (1, 0) to match other system messages
  - Removed checkmark/x symbols for cleaner look
  
  Now "Session exported to: filename.html" appears dimmed with proper spacing, just like "Thinking level: off"

  - Smaller, more compact header (16px instead of 20px)
  - Info items now stack vertically with consistent labels (80px width)
  - Reduced padding and spacing for cleaner look
  - Labels aligned to left, values aligned to baseline
  
  The header is now much less cramped and easier to read.

• Add click-to-expand and system prompt display to HTML export

  **Click-to-expand functionality:**
  - Truncated tool outputs are now clickable to show full content
  - Works for bash (>5 lines), read (>10 lines), write (>10 lines)
  - Displays "... (N more lines) - click to expand" hint in cyan
  - Smooth toggle between preview and full output
  - Cursor changes to pointer on hover
  
  **System prompt and tools display:**
  - Added system prompt section with yellow header on dark brownish background
  - Shows all available tools with names and descriptions
  - Both sections appear before messages for context
  - Subtle yellow/brown theme (rgb(60, 55, 40)) that's not too bright
  
  The HTML export now provides better interactivity for large outputs and gives full context about the agent's configuration.

• Rewrite HTML export to match TUI visual style exactly

  Complete overhaul of export-html.ts to replicate the TUI renderer's visual design:
  
  **Exact TUI color matching:**
  - User messages: rgb(52, 53, 65) dark slate background
  - Tool pending: rgb(40, 40, 50) dark blue-gray
  - Tool success: rgb(40, 50, 40) dark green
  - Tool error: rgb(60, 40, 40) dark red
  - Body background: rgb(24, 24, 30) very dark
  - Text colors matching chalk: cyan for paths, dimmed gray for output
  
  **Tool formatting (matching ToolExecutionComponent):**
  - bash: Bold `$ command`, dimmed output (max 5 lines)
  - write: Bold header with cyan path, line count, content preview (max 10 lines)
  - read: Bold header with cyan path, content preview (max 10 lines)
  - edit: Bold header with cyan path, unified diff with line numbers
  - All tools show "... (N more lines)" indicators
  
  **Additional improvements:**
  - Use session filename + .html for default output
  - Shorten paths with tilde notation (~)
  - Replace tabs with 3 spaces
  - Monospace font matching terminal aesthetic
  - Minimal, clean design with no borders/boxes
  - Print-friendly styles
  
  The HTML export now looks identical to the TUI version.

• Fix coding agent tools to return error content instead of throwing

  Tools now resolve with error messages in content blocks rather than
  rejecting the promise. This matches the expected behavior where tools
  always return a result, with errors indicated in the text content.
  
  - read: Return error content for missing files
  - edit: Return error content for missing files, text not found, multiple matches
  - bash: Return error content for command failures, timeouts, and aborts
  - All tools now include required details field in error results

• Add image support in tool results across all providers

  Tool results now use content blocks and can include both text and images.
  All providers (Anthropic, Google, OpenAI Completions, OpenAI Responses)
  correctly pass images from tool results to LLMs.
  
  - Update ToolResultMessage type to use content blocks
  - Add placeholder text for image-only tool results in Google/Anthropic
  - OpenAI providers send tool result + follow-up user message with images
  - Fix Anthropic JSON parsing for empty tool arguments
  - Add comprehensive tests for image-only and text+image tool results
  - Update README with tool result content blocks API

• Search through all messages in session, not just first message

  - SessionManager now collects text from all user and assistant messages
  - Added allMessagesText field containing concatenated message text
  - Search now matches against all messages in a session

  - Add scrolling with max 5 visible sessions at a time
  - Add scroll indicator showing position (e.g., (3/15))
  - Add blank line spacing between session items
  - Ctrl+C now exits process (process.exit(0)) instead of canceling
  - Escape still cancels and returns to main menu
  - Enter in search box selects current session

• Add custom session events for thinking level and model changes

  Session manager changes:
  - Add ThinkingLevelChangeEntry and ModelChangeEntry types
  - Add saveThinkingLevelChange() and saveModelChange() methods
  - Update loadThinkingLevel() to also check for thinking_level_change events
    (not just session headers)
  
  TUI changes:
  - Pass SessionManager to TuiRenderer constructor
  - Call saveThinkingLevelChange() when user changes thinking level via /thinking
  - Store session manager as instance variable for future use
  
  This ensures thinking level changes during a session are persisted
  and correctly restored on --continue.

• Fix viewport width issues in thinking selector and text rendering

  Thinking selector fix:
  - Replace hardcoded 50-character borders with DynamicBorder component
    that adjusts to viewport width
  - Prevents crash when terminal is resized narrow
  
  Text/Markdown rendering fixes:
  - Fix Markdown wrapSingleLine to check if adding next character would
    exceed width BEFORE adding it (was checking AFTER, causing lines to
    be 1 character too long)
  - Add word truncation in Text component for words longer than
    contentWidth (prevents long unbreakable words from exceeding width)
  
  These fixes prevent "Rendered line exceeds terminal width" errors.

  - Use hardcoded visual width for arrow prefix instead of string length
    which includes ANSI codes
  - Truncate scroll indicator text to prevent exceeding terminal width
  - Fixes crash when terminal is resized narrow and arrow keys are pressed
  
  Thinking level fix:
  - Restore thinking level even if it's "off" (removed !== "off" check)
  - This ensures the thinking level selector shows the correct state on continue

• Show "Aborted" text when aborting text generation during streaming

  Update streaming component with final message in message_end event.
  The final message includes the stopReason, which allows the component
  to render "Aborted" text for aborted text generation.
  
  Now behavior is consistent:
  - Abort during text generation (no tool calls) → shows red "Aborted"
  - Abort during tool call streaming → tool components turn red

• Fix aborted tool display when continuing sessions

  Two fixes for rendering aborted tools in --continue mode:
  
  1. In renderInitialMessages: Check if assistant message was aborted/errored
     and immediately mark tool execution components as failed instead of
     leaving them in pending state.
  
  2. In AssistantMessageComponent: Don't show "Aborted" text when there are
     tool calls in the message, since the tool execution components will
     show the error state themselves. This prevents duplicate error messages.
  
  Now aborted tools show properly as red with "Operation aborted" message,
  without the duplicate "Aborted" text above them.

• Mark pending tool components as aborted when streaming is interrupted

  When user presses Esc during tool argument streaming, the assistant
  message ends with stopReason="aborted" but tool execution never starts.
  Now we check for aborted/error stopReasons in message_end and update
  all pending tool execution components to show red error state with
  "Operation aborted" message.
  
  This fixes the issue where tool components stayed stuck in blue/pending
  state after aborting during JSON streaming.

• Make file operations properly abortable with async operations

  Replace synchronous file operations with async Promise-based operations
  that listen to abort signals during execution:
  - read, write, edit now use fs/promises async APIs
  - Add abort event listeners that reject immediately on abort
  - Check abort status before and after each async operation
  - Clean up event listeners properly
  
  This ensures pressing Esc during file operations shows red error state.

• Add abort signal handling to read, write, and edit tools

  All tools now check the abort signal before executing and throw
  "Operation aborted" error if the signal is already aborted.
  This ensures consistent abort behavior across all tools.

• Fix tab rendering in TUI components

  Replace tabs with 3 spaces for consistent rendering and width calculation:
  - Updated visibleWidth() to normalize tabs before measuring
  - Updated Text and Markdown components to replace tabs when rendering
  - Updated tool-execution display for read/write tools to replace tabs
  
  This fixes background color rendering issues when displaying files with tab indentation.
