Remove trailing generation-wrapper markup (</content>, plus </invoke> in the
tutorial) that had leaked at EOF into eleven committed Phase 7 reference,
tutorial, evidence, and OKF-journal files.
Sync the stated suite counts in the current-state docs (tutorial,
scenario-explorer reference, verification-commands reference, and OKF journal)
to the verified results: test:phase7 49, test:browser:phase7 25,
docs:validate 73 files / 28 OKF concepts / 5 indexes. Drop a brittle wall-clock
timing from the journal. The dated 7F verification evidence and log.md milestone
entry keep their point-in-time 45/19 figures on purpose.
Add a wrapper-markup guard to docs:validate (via scripts/lib/doc-wrappers.mjs)
that fails with the exact file and line when generator envelope tags reappear,
plus a node:test regression suite wired into the package test script.
