plan: phase 'cfold' — collapse functional/+playwright/ into custom/ + full !testme recipe sweep (queued after drone)

The functional/playwright split is purely organizational (discovery globs both
with no branching; same custom tier -> L4 rung, same fixtures, same failure
semantics). Migrate all custom tests to one custom/ folder; M1 proves coverage
identical before/after (no silent drops), M2 is a full real-CI !testme sweep
across all recipes confirming levels unchanged. cfold becomes the last phase so
the queued /upgrade-all fires after it (folder change verified before upgrade).

+- Operator: collapse custom-test folders functional/ + playwright/ → one custom/ folder
+  (the split is purely organizational — verified: discovery.py globs both with no
+  branching, same tier/rung/fixtures/failure semantics). Plan:
+  plan-phase-cfold-custom-folder.md. M2 = full !testme recipe sweep proving no recipe's
+  custom tests silently dropped + levels unchanged (the operator-required sweep).
+- .phases-spec now …drone;cfold (10 phases). cfold is the new LAST phase, so the
+  .run-upgrade-on-complete hook fires /upgrade-all AFTER cfold — correct order (folder
+  change swept-green before the weekly upgrade runs). Watchdog bounced to load it.
