Juan DenisandClaude Opus 4.8 15fb6ebae0 feat(wordpress): safe update manager — snapshot, rollback, schedule (#29)
Background safe update (Docker-correct, via wp_cli): record pre-update versions
-> wp db export a DB snapshot (600s timeout via a new wp_cli timeout param so a
large DB is never truncated; ABORTS if the snapshot fails) -> apply updates only
to components with an available update minus an exclusion list -> a quiet,
side-effect-free health probe (wp eval + HTTP probe; does NOT fire #27 alerts)
-> if the update regressed a previously-healthy site, AUTO-ROLLBACK: version-pin
each updated component back (--force --skip-plugins --skip-themes, so it runs
even on a fatally-broken site) + re-import the snapshot -> re-check -> persist a
WordPressUpdateRun report. The snapshot is kept for manual restore whenever the
site does not end verified-healthy.

A per-site cron schedule + exclusion list is driven by a new daemon-thread
scheduler bounded by a concurrency semaphore (a shared 3am cron can't stampede
the host). New model WordPressUpdateRun + auto_update_schedule/auto_update_exclude
columns (Alembic 012). New Updates tab (run-now, schedule, exclusions, history).

Also fixes a latent #26/#27 bug: EnvironmentHealthService.check_health returned
'unknown' for every production site (_get_compose_path needs a container_prefix
they lack), making uptime/incidents/alerts inert for the primary site type — now
falls back to the Application root_path compose.

Deferred: staging-first promotion (needs a staging env + env-pipeline
orchestration). Verified: backend py_compile, frontend lint-clean (full build was
blocked only by a concurrent agent's in-progress AI import, not #29 code),
2-lens adversarial review (blockers fixed: production health gating, DB-import
timeout; majors fixed: scheduler stampede, snapshot-abort).
