• Fix edit tool failing on Windows due to CRLF line endings

  Normalize line endings to LF before matching, restore original style on write.
  Files with CRLF now match when LLMs send LF-only oldText.

• feat(coding-agent): implement new compaction system with overflow recovery

  Phase 1: Updated compaction.ts
  - findCutPoint now returns CutPointResult with isSplitTurn and turnStartIndex
  - Can cut at user, assistant, or bashExecution messages (never tool results)
  - Added turnPrefixSummary support for split turns (parallel summarization)
  - estimateTokens helper for context size estimation
  
  Phase 2: Updated session-manager.ts
  - CompactionEntry now has optional turnPrefixSummary field
  - loadSessionFromEntries injects both summaries when turn was split
  
  Phase 3: Updated agent-session.ts
  - Overflow detection via isContextOverflow after agent_end
  - Proactive compaction check on turn_end before next LLM call
  - _abortingForCompaction flag to skip saving aborted messages
  - Auto-retry after overflow recovery or proactive compaction
  - New event fields: reason (overflow/threshold), willRetry
  
  Phase 4: Updated interactive-mode.ts
  - Shows reason in compaction status (Context overflow detected...)
  - Shows retry status after compaction
  
  Tests updated for new CutPointResult return type.

• Fix agent event ordering: update state before emitting events

  Previously, Agent.emit() was called before state was updated (e.g., appendMessage).
  This meant event handlers saw stale state - when message_end fired,
  agent.state.messages didn't include the message yet.
  
  Now state is updated first, then events are emitted, so handlers see
  consistent state that matches the event.

• fix: RPC mode session management not saving sessions

  Since version 0.9.0, RPC mode (--mode rpc) was not saving messages to
  session files. The agent.subscribe() call with session management logic
  was only present in the TUI renderer after it was refactored.
  
  RPC mode now properly saves sessions just like interactive mode.
  
  Added test for RPC mode session management to prevent regression.
  
  Fixes #83

• feat(coding-agent): add read-only exploration tools (grep, find, ls) and --tools flag

  Add grep, find, and ls tools for safe code exploration without modification risk.
  These tools are available via the new --tools CLI flag.
  
  - grep: Uses ripgrep (auto-downloaded) for fast regex searching. Respects .gitignore,
    supports glob filtering, context lines, and hidden files.
  - find: Uses fd (auto-downloaded) for fast file finding. Respects .gitignore, supports
    glob patterns, and hidden files.
  - ls: Lists directory contents with proper sorting and directory indicators.
  - --tools flag: Specify available tools (e.g., --tools read,grep,find,ls for read-only mode)
  - Dynamic system prompt adapts to selected tools with relevant guidelines

• 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)
