  • 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.

  • WIP: Major cleanup - move Attachment to consumers, simplify agent API 
    - Removed Attachment from agent package (now in web-ui/coding-agent)
- Agent.prompt now takes (text, images?: ImageContent[])
- Removed transports from web-ui (duplicate of agent package)
- Updated coding-agent to use local message types

  • WIP: Remove global state from pi-ai OAuth/API key handling 
    - Remove setApiKey, resolveApiKey, and global apiKeys Map from stream.ts
- Rename getApiKey to getApiKeyFromEnv (only checks env vars)
- Remove OAuth storage layer (storage.ts deleted)
- OAuth login/refresh functions now return credentials instead of saving
- getOAuthApiKey/refreshOAuthToken now take credentials as params
- Add test/oauth.ts helper for ai package tests
- Simplify root npm run check (single biome + tsgo pass)
- Remove redundant check scripts from most packages
- Add web-ui and coding-agent examples to biome/tsgo includes

coding-agent still has compile errors - needs refactoring for new API

  • Refactor subagent tool, fix custom tool discovery, fix JSON mode stdout flush 
    Breaking changes:
- Custom tools now require index.ts entry point in subdirectory
  (e.g., tools/mytool/index.ts instead of tools/mytool.ts)

Subagent tool improvements:
- Refactored to use Message[] from ai package instead of custom types
- Extracted agent discovery to separate agents.ts module
- Added parallel mode streaming (shows progress from all tasks)
- Added turn count to usage stats footer
- Removed redundant Query section from scout output

Fixes:
- JSON mode stdout flush: Fixed race condition where pi --mode json
  could exit before all output was written, causing consumers to
  miss final events

Also:
- Added signal/timeout support to pi.exec() for custom tools and hooks
- Renamed pi-pods bin to avoid conflict with pi

  • Custom tools with session lifecycle, examples for hooks and tools 
    - Custom tools: TypeScript modules that extend pi with new tools
  - Custom TUI rendering via renderCall/renderResult
  - User interaction via pi.ui (select, confirm, input, notify)
  - Session lifecycle via onSession callback for state reconstruction
  - Examples: todo.ts, question.ts, hello.ts

- Hook examples: permission-gate, git-checkpoint, protected-paths

- Session lifecycle centralized in AgentSession
  - Works across all modes (interactive, print, RPC)
  - Unified session event for hooks (replaces session_start/session_switch)

- Box component added to pi-tui

- Examples bundled in npm and binary releases

Fixes #190
