feat(linkedin-studio): SB-S3d — operations.md ops centre (strategy-advisor reader) [skip-docs]

Make brain/operations.md a READ tributary — the "operations centre" half of the
second brain. strategy-advisor now reads the dated "who I am now" anchor and
honours the frozen-past-self guard: when a profile.md fact predates or
contradicts the anchor, the anchor deprecates it (advisory/reader-side; NO
consolidate-engine change). Anti-sycophancy is INVERTED vs the profile —
profile facts stay evidence-to-TEST, the user-declared anchor is honoured.

- scaffold.ts operationsSeed(): dated-anchor convention (_As of YYYY-MM-DD:_) +
  Plans/Ideas guidance; existence-skip idempotency preserved (no-clobber green).
- strategy-advisor.md: operations.md in Step 0 context-load + a consumption
  contract (anchor authoritative, inversion, plans-vs-ideas, graceful absence).
- test-runner.sh Section 16e: 2 unconditional checks (non-vacuity self-test +
  wiring grep, sibling-file decoy); ASSERT_BASELINE_FLOOR 80->82; BRAIN floor 113->114.
- architecture.md:80: build-row reconciled (S3d done; S3e = dead content-history
  retirement + triple-post reconciliation = the new LAST S3 slice).

Gate 97/0/0; brain 114/114. TDD: RED proven (16e Check B + the scaffold
dated-anchor test both failed pre-fix) before GREEN. Splits the old S3d charter;
the hygiene half is deferred to SB-S3e. Light-Voyage hardened (scope-guardian
ALIGNED, brief-reviewer + plan-critic folds in docs 0061bf2).
