When the HTTP tool detects a missing credential for a registered host:
1. EffectBridgeAdapter emits SSE AuthRequired event (best-effort, for
   connected frontends — silently dropped for missions/background threads)
2. Error flows back to LLM as normal ActionResult (non-blocking)
3. LLM tells the user to authenticate

This avoids the blocking interruption approach which would hang mission
threads and sub-threads that have no channel context.

Engine additions:
- EngineError::NeedAuthentication variant for structured auth failures
- ThreadOutcome::NeedAuthentication for batch interruption when needed
- structured.rs handles NeedAuthentication by interrupting the batch
  (stops subsequent calls, returns outcome to orchestrator)
- Auth callback on EffectBridgeAdapter (optional, set by router for SSE)
- extract_credential_name parser for HTTP tool error messages
- routine_* tools added to is_v1_only_tool blocklist

Safety: added 5-minute timeout to await_thread_outcome to prevent
infinite hangs (e.g. after denied tool approval where thread fails
to resume).

Tests: 3 structured executor tests (NeedAuthentication interrupts batch,
stops subsequent calls, regular errors don't interrupt) + 7 effect
adapter tests (credential extraction, callback firing, v1-only tools).

Also adds Linear API skill (skills/linear/SKILL.md).
