• feat(coding-agent): add interactive-shell.ts extension example

  Demonstrates running interactive commands (vim, git rebase, htop, etc.)
  with full terminal access using user_bash event and ctx.ui.custom().
  
  - Auto-detects interactive commands from built-in list
  - !i prefix to force interactive mode
  - Configurable via INTERACTIVE_COMMANDS/INTERACTIVE_EXCLUDE env vars
  
  closes #532

• Fix --no-skills flag not preventing skills from loading

  The --no-skills flag set options.skills = [] in main.ts, but the
  interactive mode UI would rediscover skills anyway because it called
  loadSkills() directly instead of using the already-loaded skills.
  
  Changes:
  - Add AgentSession.skills and AgentSession.skillWarnings properties
  - discoverSkills() now returns { skills, warnings } instead of Skill[]
  - Interactive mode uses session.skills instead of calling loadSkills()
  - Update SDK docs and examples for new return type
  
  Fixes #577

• feat(coding-agent): add user_bash event and theme API extensions

  - user_bash event for intercepting ! and !! commands (#528)
  - Extensions can return { operations } or { result } to redirect/replace
  - executeBashWithOperations() for custom BashOperations execution
  - session.recordBashResult() for extensions handling bash themselves
  - Theme API: getAllThemes(), getTheme(), setTheme() on ctx.ui
  - mac-system-theme.ts example: sync with macOS dark/light mode
  - Updated ssh.ts to use user_bash event

• Allow extensions to modify system prompt in before_agent_start

• feat(coding-agent): add pluggable operations for remote tool execution

  Adds optional operations parameter to create*Tool functions enabling
  delegation to remote systems (SSH, containers, etc.):
  
  - ReadOperations: readFile, access, detectImageMimeType
  - WriteOperations: writeFile, mkdir
  - EditOperations: readFile, writeFile, access
  - BashOperations: exec (with streaming, signal, timeout)
  
  Add ssh.ts example demonstrating --ssh flag for remote execution.
  Built-in renderers used automatically for overrides without custom renderers.
  
  fixes #564

• feat(coding-agent): use built-in renderers for tool overrides without custom renderers

  When overriding a built-in tool (read, bash, edit, write, grep, find, ls)
  without providing renderCall/renderResult, the built-in renderer is now
  used automatically. This allows wrapping built-in tools for logging or
  access control without reimplementing the UI (syntax highlighting, diffs, etc.).

• feat(coding-agent): add timeout option to extension dialogs with live countdown

  Extension UI dialogs (select, confirm, input) now support a timeout option
  that auto-dismisses with a live countdown display. Simpler alternative to

  forward timeout to clients.

• Extensions: add pi.sendUserMessage() for sending user messages

  Adds sendUserMessage() to the extension API, allowing extensions to send
  actual user messages (role: user) rather than custom messages. Unlike
  sendMessage(), this always triggers a turn and behaves as if the user
  typed the message.
  
  - Add SendUserMessageHandler type and sendUserMessage() to ExtensionAPI
  - Wire handler through loader, runner, and all modes
  - Implement via prompt() with expandPromptTemplates: false
  - Add send-user-message.ts example with /ask, /steer, /followup commands
  - Document in extensions.md

  Includes example extension demonstrating context usage display.

• feat(coding-agent): add event bus for tool/hook communication (#431)

  * feat(coding-agent): add event bus for tool/hook communication
  
  Adds pi.events API enabling custom tools and hooks to communicate via
  pub/sub. Tools can emit events, hooks can listen. Shared EventBus instance
  created per session in createAgentSession().
  
  - EventBus interface with emit() and on() methods
  - on() returns unsubscribe function
  - Threaded through hook and tool loaders
  - Documented in hooks.md and custom-tools.md

  * docs: note async handler error handling for event bus
  
  * feat(coding-agent): add sendMessage to tools, nextTurn delivery mode
  
  - Custom tools now have pi.sendMessage() for direct agent notifications
  - New deliverAs: 'nextTurn' queues messages for next user prompt
  - Fix: hooks and tools now share the same eventBus (was isolated before)
  
  * fix(coding-agent): nextTurn delivery should always queue, even when streaming

    setActiveTools()

• refactor: address PR feedback - merge setWidget, use KeyId for shortcuts

  1. Merge setWidget and setWidgetComponent into single overloaded method
     - Accepts either string[] or component factory function
     - Uses single Map<string, Component> internally
     - String arrays wrapped in Container with Text components
  
  2. Use KeyId type for registerShortcut instead of plain string
     - Import Key from @mariozechner/pi-tui
     - Update plan-mode example to use Key.shift('p')
     - Type-safe shortcut registration
  
  3. Fix tool API docs
     - Both built-in and custom tools can be enabled/disabled
     - Removed incorrect 'custom tools always active' statement
  
  4. Use matchesKey instead of matchShortcut (already done in rebase)
