feat(linkedin-studio): SB-S3a — wire strategy-advisor as first brain/profile.md reader [skip-docs]

The second brain now feeds generation: strategy-advisor reads brain/profile.md
as evidence-to-test (anti-sycophancy default, graceful absence on fresh installs).
First end-to-end proof of capture → consolidate → read-back-into-generation.

- agents/strategy-advisor.md: brain/profile.md added to Step 0 Load Context + a
  consumption subsection (Static/Dynamic layers, evidence_count/last_seen weighting,
  anti-sycophancy counter-pressure, silent degrade when the file is absent).
- scripts/test-runner.sh: new Section 16d (Brain Profile Reader) — 2 UNCONDITIONAL
  checks (non-vacuity self-test with legacy-path/lowercase decoy + exact-literal
  wiring grep on strategy-advisor.md), ASSERT_BASELINE_FLOOR 78→80, header
  enumeration extended. Gate 93→95/0/0; brain floor 82 untouched.
- docs/second-brain/consolidation-loop.md: reconciled the stale "no reader yet"
  honest-limit to the true partial state (one reader; broader consumption deferred).

TDD: RED (only the wiring grep failed, exit 1) → GREEN (95/0/0). READ-only — the
brain consolidate --apply --confirm gate stays the sole writer. SC4 (graceful
absence) verified by inspection; SC5 (read-back) deferred to a reloaded session
(honest — agent prompts load at session start). S3a scope held: one reader, no
parser, no id-threading.

 Use demographics data to compare the user's **intended** audience vs **actual** engagers when making strategic recommendations.
 
+### Consuming the evolving profile (brain/profile.md)
+
+The second-brain profile is a consolidated, evidence-weighted picture of the user, grown over time by the brain motor (mutated ONLY via `brain consolidate --apply --confirm` — you never write it). It has two layers:
+
+- **`## Static`** — stable, high-confidence facts about the user.
+- **`## Dynamic`** — emerging facts still accruing evidence.
+
+Each fact line carries `evidence_count` and `last_seen`. Weight by strength and recency: a higher `evidence_count` and a more recent `last_seen` are a stronger, fresher signal than a thin or stale one.
+
+**Anti-sycophancy (binding):** Treat every profile fact as **evidence to TEST**, not flattery — counter-pressure it against the analytics and state each time you use it (e.g. *the profile says you lean toward X, but your recent imports show Y — test that before recommending*). The profile informs your recommendations; it never dictates them and never flatters the user.
+
+**Graceful absence:** If `brain/profile.md` is missing or empty (fresh installs have no brain yet), proceed silently on the other context sources — no error, and no note about a missing profile.
