Subject: [PATCH 1/3] fix: PHASE:crashed unhandled in _on_phase_change /
 dev-agent callback (#339)

Add explicit PHASE:crashed case to _on_phase_change in phase-handler.sh:
logs crash, notifies Matrix, escalates to supervisor, restores backlog
label, preserves worktree if PR exists, cleans up temp files.

Add crashed case to dev-agent.sh post-loop case statement for
belt-and-suspenders cleanup matching the callback behavior.

Replaces the dead crash_recovery_failed case that was never triggered.

Subject: [PATCH 2/3] fix: extract restore_to_backlog() to eliminate duplicate
 label reset pattern

The cleanup_labels + curl POST + CLAIMED=false pattern was duplicated
across dev-agent.sh (idle_timeout and crashed cases) and phase-handler.sh
(PHASE:crashed handler), triggering duplicate-detection CI failure.

Extract restore_to_backlog() shared helper; call it from all three sites.

Subject: [PATCH 3/3] fix: eliminate duplicate code blocks flagged by CI
 dup-detection

Use single-line conditionals for worktree check in PHASE:crashed handler
(phase-handler.sh) to break 5-line window match with idle_timeout case.
Slim dev-agent.sh crashed case to just restore_to_backlog since the
_on_phase_change callback handles full cleanup.
