• 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)

• feat(hooks): add setWidgetComponent for custom TUI components

  - New ctx.ui.setWidgetComponent(key, factory) method
  - Allows custom Component to render as widget without taking focus
  - Unlike custom(), widget components render inline above editor
  - Components are disposed when cleared or replaced
  - Falls back to no-op in RPC/print modes

• feat(coding-agent): add hook API for CLI flags, shortcuts, and tool control

  Hook API additions:
  - pi.getTools() / pi.setTools(toolNames) - dynamically enable/disable tools
  - pi.registerFlag(name, options) / pi.getFlag(name) - register custom CLI flags
  - pi.registerShortcut(shortcut, options) - register keyboard shortcuts
  
  Plan mode hook (examples/hooks/plan-mode.ts):
  - /plan command or Shift+P shortcut to toggle
  - --plan CLI flag to start in plan mode
  - Read-only tools: read, bash, grep, find, ls
  - Bash restricted to non-destructive commands (blocks rm, mv, git commit, etc.)
  - Interactive prompt after each response: execute, stay, or refine
  - Shows plan indicator in footer when active
  - State persists across sessions

  New example hook: plan-mode.ts
  - Claude Code-style read-only exploration mode
  - /plan command toggles plan mode on/off
  - Plan mode tools: read, bash, grep, find, ls
  - Edit/write tools disabled in plan mode
  - Injects context telling agent about restrictions
  - After each response, prompts to execute/stay/refine

• fix(coding-agent): prevent full re-renders during write tool streaming

  Move line count from header to footer to avoid changing the first line
  during streaming, which was triggering full screen re-renders in the
  TUI's differential rendering logic.

• Split HookContext and HookCommandContext to prevent deadlocks

  HookContext (all events):
  - isIdle() - read-only state check
  - hasQueuedMessages() - read-only state check
  - abort() - fire-and-forget, does not wait
  
  HookCommandContext (slash commands only):
  - waitForIdle() - waits for agent to finish
  - newSession(options?) - create new session
  - branch(entryId) - branch from entry
  - navigateTree(targetId, options?) - navigate session tree
  
  Session control methods moved from HookAPI (pi.*) to HookCommandContext (ctx.*)
  because they can deadlock when called from event handlers that run inside
  the agent loop (tool_call, tool_result, context events).

• Add session management and agent state methods to hooks API

  HookAPI additions:
  - pi.newSession(options?) - create new session with optional setup callback
  - pi.branch(entryId) - branch from a specific entry
  - pi.navigateTree(targetId, options?) - navigate the session tree
  
  HookContext additions:
  - ctx.isIdle() - check if agent is streaming
  - ctx.waitForIdle() - wait for agent to finish
  - ctx.abort() - abort current operation
  - ctx.hasQueuedMessages() - check for queued user messages
  
  These enable hooks to programmatically manage sessions (handoff, templates)
  and check agent state before showing interactive UI.
  
  Fixes #388

• refactor(coding-agent): fix compaction for branched sessions, consolidate hook context types

• refactor(hooks): split session events into individual typed events

  Major changes:
  - Replace monolithic SessionEvent with reason discriminator with individual
    event types: session_start, session_before_switch, session_switch,
    session_before_new, session_new, session_before_branch, session_branch,
    session_before_compact, session_compact, session_shutdown
  - Each event has dedicated result type (SessionBeforeSwitchResult, etc.)
  - HookHandler type now allows bare return statements (void in return type)
  - HookAPI.on() has proper overloads for each event with correct typing
  
  Additional fixes:
  - AgentSession now always subscribes to agent in constructor (was only
    subscribing when external subscribe() called, breaking internal handlers)
  - Standardize on undefined over null throughout codebase
  - HookUIContext methods return undefined instead of null
  - SessionManager methods return undefined instead of null
  - Simplify hook exports to 'export type * from types.js'
  - Add detailed JSDoc for skipConversationRestore vs cancel
  - Fix createBranchedSession to rebuild index in persist mode
  - newSession() now returns the session file path
  
  Updated all example hooks, tests, and emission sites to use new event types.

• Hook API: replace send() with sendMessage(), add appendEntry() and registerCommand()

  Breaking changes to Hook API:
  - pi.send(text, attachments?) replaced with pi.sendMessage(message, triggerTurn?)
    - Creates CustomMessageEntry instead of user messages
    - Properly handles queuing during streaming via agent loop
    - Supports optional turn triggering when idle
  - New pi.appendEntry(customType, data?) for hook state persistence
  - New pi.registerCommand(name, options) for custom slash commands
  - Handler types renamed: SendHandler -> SendMessageHandler, new AppendEntryHandler
  
  Implementation:
  - AgentSession.sendHookMessage() handles all three cases:
    - Streaming: queues message with _hookData marker, agent loop processes it
    - Not streaming + triggerTurn: appends to state/session, calls agent.continue()
    - Not streaming + no trigger: appends to state/session only
  - message_end handler routes based on _hookData presence to correct persistence
  - HookRunner gains getRegisteredCommands() and getCommand() methods
  
  New types: HookMessage<T>, RegisteredCommand, CommandContext

• Add CustomMessageEntry rendering infrastructure

  - Add renderCustomMessage to HookAPI for registering custom renderers
  - Add CustomMessageRenderer type and CustomMessageRenderOptions
  - Store customMessageRenderers in LoadedHook
  - Add getCustomMessageRenderer(customType) to HookRunner
  - SessionContext.entries now aligned with messages (same length, corresponding indices)
  
  TUI can now correlate messages with their source entries to identify
  custom_message entries and use hook-provided renderers.

• Refactor SessionEventBase to pass sessionManager and modelRegistry

  Breaking changes to hook types:
  - SessionEventBase now passes sessionManager and modelRegistry directly
  - before_compact: passes preparation, previousCompactions (newest first)
  - before_switch: has targetSessionFile; switch: has previousSessionFile
  - Removed resolveApiKey (use modelRegistry.getApiKey())
  - getSessionFile() returns string | undefined for in-memory sessions
  
  Updated:
  - All session event emissions in agent-session.ts
  - Hook examples (custom-compaction.ts, auto-commit-on-exit.ts, confirm-destructive.ts)
  - Tests (compaction-hooks.test.ts, compaction-hooks-example.test.ts)
  - export-html.ts guards for in-memory sessions

• Fix API key priority and compaction bugs

  - getEnvApiKey: ANTHROPIC_OAUTH_TOKEN now takes precedence over ANTHROPIC_API_KEY
  - findCutPoint: Stop scan-backwards loop at session header (was decrementing past it causing null preparation)
  - generateSummary/generateTurnPrefixSummary: Throw on stopReason=error instead of returning empty string
  - Test files: Fix API key priority order, use keepRecentTokens=1 for small test conversations
