v0.21.0

Release date: 2026-06-22

Added

Added Codex-style command hooks across session, tool, compaction, stop, and sub-agent lifecycle events, with trust review through the CLI, web API, and Settings UI (314d74fc, 2cd4fcdc).
Added Firecrawl-backed web_search and made read_web_url use Firecrawl scrape before falling back to markdown.new (6f056117).
Added an orchestrator project sub-agent and updated /orchestrate so user-provided plans skip the planner and start directly at the worker (31de49ee).
Added desktop and sound notifications when an interactive session finishes while the user is AFK (f79caa9b).

/orchestrate now enforces one sequential task flow with worker, reviewer/fixer, and code-quality/fixer gates, plus clearer sub-agent delegation rules (3f87a0fd, 6c3f0a2c, 3c1f9abb).
Long user inputs in the session timeline collapse behind a safer expand control, reducing noisy transcript scrolling (804cda77).
Command naming and documentation now consistently use code-quality-review for the code-quality review workflow (49fff5bb).

Corrected the sub-agent key used by /orchestrate, restoring the expected code-quality reviewer delegation (1b0fec86).
Session-finished notifications now fire only on the AFK working-to-ready edge instead of treating successful interactive turns as ended live sessions (c93cb3c7).

Documented hooks configuration, trust review, managed hook semantics, dangerous bypass mode, matcher behavior, hook payloads, outputs, and current limitations (2cd4fcdc).
Updated tool and customization docs for the Firecrawl-backed web tools and the current built-in web tool group (6f056117).

Refactored session/runtime, hook, provider, and tool execution internals to support hook lifecycle dispatch, guarded continuations, and clearer code structure (70c296cb).
