v0.9.0

What's New

Hooks system (#106, #107)

• Full session hooks support using the official CLI format (shell commands with JSON stdin/stdout)
  workspace (opt-in via allowWorkspaceHooks)
• Hooks visible in /tools output alongside MCP servers and skills
• deny hooks short-circuit tool execution; ask hooks trigger an interactive permission prompt in chat
• Hook permissions always prompt per-invocation (no "always approve" option)
• Async spawn execution with manual SIGKILL timeout for reliable cleanup

Multi-turn content preservation (#108)

• Fixed a bug where multi-turn streaming responses lost earlier only the last turn's text survived in chatcontent
• Each turn now finalizes as its own chat message on turn_end, so all content persists
• Thread context preserved across turns via channelThreadRoots map
• Stale thread roots cleaned up on /new, /stop, errors, and session idle (including mid-turn command paths)
• Permission and user-input prompts now save thread context before finalizing streams
