v0.3.0

This release pairs extensibility — config-defined hooks that now fire at runtime, a SessionStart context-injection surface, and a proactive skill nudge — with a reliability pass on the background sub-agent supervisor, hardening the EventHub and worker channels against panics, unbounded memory, blocked readers, and idle-timeout overshoot. It also adds a user-facing extended-thinking toggle and tightens the Google provider's fault classification.

Added

• Config-defined hooks execute at runtime (#121): [[hooks.*]] handlers are now built into executing command/http handlers and composed into the agent's hook chain. (#126)
• SessionStart context-injection hook surface (#106): session_start hooks can splice additional_context into the system prompt before turn 1. (#122)
• Proactive skill-invocation nudge (#56): the system prompt lists loaded skills and nudges the model to invoke a matching one, gated by tools.skill_guidance. (#105)
• User-facing extended-thinking toggle (#100): control extended thinking independently of the effort level. (#110)
• Shared cross-cutting area labels (#109). (#123)

Changed

• Immediate slash commands (#13): 19 eligible slash commands now execute immediately. (#104)

Fixed

• Inbound frame reader no longer blocks on a full worker channel (#118). (#134)
• Worker idle timeout uses a deadline to remove overshoot (#119). (#133)
• EventHub history is bounded to cap worker memory (#116). (#132)
• Inherited workers honor parent allow/deny rules (#114). (#131)
• Poisoned EventHub history lock recovers instead of panicking (#113). (#130)
• Google provider fault classification for 400 context-overflow + in-band SSE faults (#111). (#129)
• /memory delete gated behind --force (#112). (#120)
• Skipped skills surfaced instead of silently dropped (#107). (#108)

Docs

• Adopted the docs/adr/ convention (#125) and centralized GitHub Pages — ADR ingestion, shared theme, rustdoc (#128).
