Pilot weekly org review cadence and prompt tuning

[ss-o]

Summary

Run the new weekly org-review workflow on a real cadence and tune the prompt/output shape based on maintainer usefulness.

Scope

• run the workflow from runbooks/org-review.md on a weekly cadence for a few iterations
• note which sections create signal versus noise
• adjust the prompt template and output shape if needed
• decide whether the review should live only as a manual maintainer workflow or gain lightweight scheduling support later

Notes

A first dry-run summary has already been recorded on z-shell/.github#410.

Status: this is the only remaining linked ZSH-8 governance item after #411, #414, and #415 closed.

Completed in the current pass:

• reconciled linked governance issues against live GitHub state
• added runbooks/new-repository.md via docs(runbooks): add repository bootstrap guide #435
• validated and closed the deprecation runbook item Add repository deprecation runbook #415
• closed Trunk caller standardization Standardize Trunk caller workflows across Z-Shell repos #408 after wiki#764 and reusable repairs fix(trunk): quote runs-on input reference #434/fix(trunk): let callers own concurrency #436

Next steps:

1. Run the weekly org review using runbooks/org-review.md on the next scheduled cadence.
2. Record signal/noise observations in this issue after each iteration.
3. Tune the prompt/output shape only after multiple runs provide evidence.
4. Decide later whether lightweight scheduling is useful.

Verification: Linear ZSH-8 has been updated with the live linked-issue state.
