test(phase6f): add V1 pilot acceptance suite; fix regression from real curriculum changes

- New platform/test/e2e-phase6f.js (17 tests): V1 manifest/exclusion correctness, the full
  V1 prerequisite graph, ROOT 01-04 re-verification, the orientation module's unlock
  behavior, optional-activity handling, the strengthened Capstone gate in both directions,
  instructor-notes RBAC on locked (not just draft) content, isolation, and an explicit
  age-independence check.
- foundations-helper.js: completeThroughRoot06/completeThroughRoot10 updated for the new
  practice-bank intro-lesson activities; new completeThroughCapstoneEligible() helper
  (ROOT 07-m03/m04 + full ROOT 09 + ROOT 12) shared by e2e-phase6f.js and both new drills.
- e2e-phase6a/6b/6d/6e.js: resume-pointer assertions updated for the new orientation
  module; e2e-phase6a.js's and e2e-phase6b.js's own inline ROOT 06/07/09/10/12 completion
  sequences updated for the new intro-lesson activities and the new root-09 Capstone
  dependency; e2e-phase6b.js's stale ROOT 09 status assertion and its draft-activity test
  (previously targeting the now fully-excluded ROOT 08) corrected.
- test-phase6d/6e-foundations-rehearsal.js: same orientation-module fix applied to the
  real-Lab dress rehearsals.

All of 6A (23/23) / 6B (26/26) / 6C (17/17) / 6D (21/21) / 6E (23/23) / 6F (17/17) verified
green on independent fresh stacks. See docs/PHASE6F_ROOT_V1_PILOT_READINESS.md.
