feat(01-13-A14-invert): A14 — invert to assert continuous-recording post-SAVE

Plan 01-09 Amendment 3 (2026-05-19) end-to-end lock. Inverted A14 to
match the reversed charter (SAVE creates zip, recording continues).

Page-side (tests/uat/extension-page-harness.ts):
- assertA14: assert badge==='REC' (was ''), popup endsWith
  'src/popup/index.html' (was ''), no-new-recovery-notif (unchanged).
- A14 name + check labels updated to reflect continuous-recording semantic.
- New constant A14_POPUP_HTML_SUFFIX for the popup endsWith check
  (ext-id-agnostic via suffix match).
- A13 docstring + diag strings refreshed: setupFreshRecording is now
  defensive (orthogonal to A12 ordering) rather than a workaround for
  the prior auto-stop. 11s settle preserved (same wall-clock cost).

Host-side (tests/uat/lib/harness-page-driver.ts):
- driveA14 docstring refreshed to mention Amendment 3 + the inverted
  contract; mechanical wrapper unchanged.

Verification:
- npm run test:uat: 15/15 GREEN
- A14 actual output:
    badge='REC'
    popup='chrome-extension://<ext-id>/src/popup/index.html'
    recoveryDelta=0
