Subject: [PATCH] watchdog: phase_done ignores placeholder '## DONE' sections
 (skipped mailu)

A Builder scaffolded 'STATUS-mailu.md' with a '## DONE / Not yet. Written
here only when ...' placeholder section; phase_done's startswith('## DONE')
matched it and auto-advanced past mailu without any of its work being done
(no recipe PR, no claim, no review). Harden phase_done: a '## DONE' heading
counts only when its first non-empty body line is not a placeholder/negation
(Not yet / pending / TBD / when all / <...> etc). Verified against all shipped
STATUS files (real DONEs still detected; mailu placeholder rejected).
