chore(daily-status): move schedule to 08:00 SGT (00:00 UTC)

[arnaudlh]

Switches the daily-repo-status workflow from the gh-aw schedule: daily fuzzy default (which had been compiling to 25 10 * * * UTC ≈ 18:25 SGT) to a fixed 0 0 * * * UTC, i.e. 08:00 SGT every day.

Why

• The fuzzy daily run had been missing days recently (last successful schedule: May 25; May 26 and May 27 skipped — typical GitHub-Actions scheduled-workflow drop behaviour).
• Pinning to an explicit UTC hour makes monitoring easier and aligns delivery with the start of the SGT workday.

Files

• .github/workflows/daily-repo-status.md — source: switched schedule: daily → explicit cron.
• .github/workflows/daily-repo-status.lock.yml — mirrors the cron change (single-line patch; full gh aw compile was skipped to avoid sweeping in unrelated tool-version drift).

Review summary

Targeted, low-risk schedule change. Reviewed the diff against daily-repo-status.md and daily-repo-status.lock.yml:

Correctness

• Time math checks out: cron: "0 0 * * *" UTC + 8h = 08:00 SGT ✅
• Source .md and compiled .lock.yml cron values are in sync (0 0 * * * in both) ✅
• All 5 checks pass (Analyze, Markdown Lint, Structural Validation, actionlint, CLA) ✅
• Skipping a full gh aw compile to avoid sweeping in unrelated drift is a reasonable trade-off given the single-line nature of the change

Minor nits (non-blocking)

1. Stale comment in daily-repo-status.lock.yml:58:

   - cron: "0 0 * * *"
     # Friendly format: daily (scattered)

   The "(scattered)" hint described the old schedule: daily fuzzy default; with an explicit cron it's now misleading. Either drop the comment or replace it with "08:00 SGT (00:00 UTC)" to match the source .md.

2. Heads-up on top-of-hour scheduling: 0 0 * * * lands on the highest-traffic GH Actions cron slot, which is the slot most prone to delays/drops. If reliability is the actual goal (the PR body cites recent missed runs), an off-peak minute like 7 0 * * * would still give an ~08:07 SGT start but with a notably better hit rate. Worth keeping in mind if days continue to be skipped after this lands.

Otherwise LGTM — clean fix for the missed-runs symptom and easier to monitor than the fuzzy default. 👍
