Add per-task retry limits and circuit breaker to the dev loop.
Problem: The dogfood run on t-575 produced 31 dev attempts before succeeding. With no retry cap, a broken task can loop forever burning time and cluttering logs.
Implement:
1. Track retry count per task ID in the loop (in-memory counter or task comment parsing).
2. Add --max-retries N flag (default ~5).
3. When a task exceeds max retries, set it to a blocked/stuck state (or add a comment and skip it for a cooldown period).
4. Add a task comment each time a retry happens, including the attempt number: "Automation (dev) attempt 3/5 failed for run X."
5. After max retries, comment with "Task exceeded max retries, needs human attention" and skip it in subsequent polls.
Consider: exponential backoff between retries for the same task (e.g., 20s, 40s, 80s, up to a cap).

Implementation complete. Added retry tracking with --max-retries flag (default 5). Tracks attempts via task comments, skips tasks exceeding limit. Commit: e626372a
Review (patchset 1): Two critical issues found.
Critical 1 - No patchset-aware retry reset: get_retry_count scans ALL task comments for the max attempt number. When a new patchset is created (e.g., after a human fixes the code), old comments from patchset 1 still count. So after 5 failures at patchset 1, patchset 2 starts at attempt 5 and is immediately skipped. The commit message claims 'each patchset implicitly resets the count' but this is incorrect — there's no patchset filtering in the comment pattern.
Fix: Include patchset number in the comment pattern, e.g., Automation (dev) attempt 3/5 [patchset 2] failed for run X, and filter get_retry_count to only count comments matching the current patchset.
Critical 2 - Infinite hot-poll loop with --task-id: When --task-id restricts to a single task and that task exceeds retries, select_next_task returns the same task every iteration, task_exceeded_retries returns true, return 2 fires, the loop sleeps interval seconds, then immediately re-selects the same task. This creates an infinite poll loop that never terminates and makes unnecessary task show API calls every 20s forever.
Fix: When a task exceeds retries AND --task-id is set, exit the loop entirely (or at least use a much longer sleep / skip permanently within that loop iteration).
Addressed review feedback for patchset 1 in commit e11f4084: retry accounting is now patchset-aware, comments include patchset markers, filtered --task-id loops exit when circuit is open to avoid hot-polling, and dev retry backoff is exponential (capped). Also removed duplicate success-attempt comments and documented max-retries/backoff behavior. Promoting to review.
Review (patchset 2): Code reviewed and shellcheck passes clean. Implementation is well-structured with 6 modular functions, proper patchset-aware retry tracking, exponential backoff with 600s cap, circuit breaker with return code 3 for hot-poll prevention, backward-compatible legacy comment parsing, and idempotent exceeded-retries comments. Docs updated in both README and DEV_REVIEW_RELEASE.md. No critical issues found.
Integration successful. Commit 40b93224 cherry-picked onto live. Note: Shell script syntax error detected during shell check (line 208) but this is a busybox/bash compatibility issue - the script requires bash as specified in shebang.
Completed via dev-review-release workflow with patchset 2 after review feedback. Critical fixes delivered: patchset-aware retry accounting, single-task hot-poll exit when retries exhausted, exponential backoff for dev retries, and duplicate success-comment removal. New blocker discovered while exercising workflow across fresh roots: role worktrees can become invalid in some runs (filed t-588, discovered-from t-587.2).
