v2.22.0

[2.22.0] - 2026-03-26

Added

• File locking for dashboard state writes using mkdir-based POSIX locking (macOS compatible)
• state_lock, state_unlock, and state_locked_update helpers in hook-helpers.sh
• Stale lock detection and automatic cleanup after 30 seconds
• Empty-output protection: jq transforms that produce empty results no longer overwrite the state file
• Active Claude session detection: agents with a running Claude process show yellow terminal icon + "ACTIVE" badge
• Repurposed worktree detection: warns when branch name ticket doesn't match commit content
• Agents sorted by active sessions first, then by most recent activity

Changed

• All state file writes (hooks, scan, PR create) now go through state_locked_update
• "Ahead" drift badge colour changed from grey to green
• Active agents cannot be marked stale

Fixed

• Dashboard stage hook resolves agent by branch to enrich scan entries instead of duplicating
• dashboard_update() resolves existing agent by branch before creating new entry
