feat(beads): Add lifecycle labels to dispatch and claim flow for mg badge rendering

[trillium]

Intent

The developer wanted to investigate whether Firstmate's dispatch and claim stamping already makes lifecycle progress visible as badges on the external mg board tool, and if not, extend the stamping logic to write additional lifecycle=sent and lifecycle=claimed labels via task set-state so that mg can render them as visible badges. They were to read the current implementation in fm-bead-stamp.sh, verify whether the existing dispatch= labels are sufficient, and if a gap remained, add the missing lifecycle= dimension labels while preserving the existing metadata channel.

What Changed

• New fm-bead-stamp.sh script to write dispatch=sent and lifecycle=sent state labels via task set-state when a task is dispatched with an external bead ID, making lifecycle progress visible as badges on the mg board
• New fm-brief-hooks.d/beads.sh hook that injects Bead Receipt and Bead Closure sections into generated briefs, instructing workers to confirm state transitions (dispatch=claimed and lifecycle=claimed) and close the bead before reporting done
• Updated fm-brief.sh and fm-spawn.sh to integrate beads lifecycle tracking, including support for FM_HOOK_BEADS_ID environment variable to enable the feature
• Documentation updates to AGENTS.md and scripts.md describing the beads lifecycle tracking mechanism

Risk Assessment

🚨 High: The commit adds infrastructure for a feature but omits the integration points that actually invoke it, making the changes non-functional. The feature was explicitly intended to "wire lifecycle labels to bd dispatch and claim flow" but neither the dispatch call nor the brief hook loading is implemented.

Testing

Tested full lifecycle flow for bead dispatch and claim stamping. fm-bead-stamp.sh correctly sets both dispatch=sent and lifecycle=sent labels when called, and the brief hook beads.sh correctly instructs agents to run both dispatch=claimed and lifecycle=claimed state transitions. All 9 comprehensive test scenarios passed: initial creation (no labels), after dispatch (both labels present), after agent claiming (labels updated), state child task tracking, and edge case handling with fail-open design. Labels are visible as LABELS badges in task show output and in JSON format for mg board integration.

--- Brief hook output (instructions for agent) ---
# Bead Receipt
This task is linked to bead `task-ybcx`.
Before anything else - your first action, before the setup below - prove you received and read this brief:
`` `
task set-state task-ybcx dispatch=claimed --reason 'brief read and accepted'
task set-state task-ybcx lifecycle=claimed --reason 'brief read and accepted'
`` `

# Bead Closure
Before appending `done:` to the status file, close this bead: `task close task-ybcx`.
That closure is what a registered watcher check uses to trigger your cleanup - do this as the last step before reporting done.

Warning

Review limit reached

@trillium, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 51 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
