Merge pull request 'fix(ci)(interim): disable status-reaper + main-red-watchdog crons (machinery-down)' (#645) from infra/interim-disable-reaper-watchdog-crons into main

RFC#420 Option-C machinery has been down ~2.5h:
- status-reaper rev2 (PR#633, merged 01:48Z): 0 'Compensated by status-reaper'
  status on the last 14 main commits. Schedule reds stranded on stale
  commits despite the rev2 sweep-last-10 design.
- main-red-watchdog: 'Failing after 10m56s' with timeout-minutes:5 — runner
  saturation queue-lag pushed it past its own timeout. No [main-red] issues
  filed during the outage despite 5 reds on HEAD e7965a0f at the high
  watermark.

Both workflows were themselves contributing to the red pileup on main +
queuing the ubuntu-latest pool. Cheap-and-safe interim: comment out the
schedule: blocks. workflow_dispatch: stays so they can be triggered
manually for debugging.

Re-enable after:
1. rev3 lands (likely scan_workflows() should LOG-and-skip rather than
   sys.exit on a malformed workflow; list_recent_commit_shas() should
   degrade gracefully)
2. Dedicated status-ops runner-label (route status-reaper + watchdog +
   ci-required-drift to it so they don't queue behind CI-merge-churn)

Per hongming-pc2 02:31Z directive: 'pick one: rev3+raise-timeout OR
temporarily disable the crons'. Choosing disable for safety while rev3
investigation proceeds.
