fix(linkedin-studio): S11 — model-name declaration drift + model-consistency lint guard

Cold full-brief re-review (S10) reached a class the S7->S9 algorithm-stat lens
never did:

BLOCKER — post-feedback-monitor published as Haiku in four surfaces
(README:259, skills/linkedin-studio:159 with wrong color Green too,
skills/linkedin-analytics:41, agents-capability-matrix:20) while
agents/post-feedback-monitor.md runs Opus. v4.0.0's Opus promotion never
reached the user-facing tables. Synced all to Opus/Lime. Refreshed
agents-capability-matrix.md (frozen at the v2.0 14-agent era): header 14->19,
+5 missing longform agents, tier counts Opus 2->8 / Haiku 1->0, longform-gate
diagram updated to the real 8-Opus-agent chain.

MAJOR — de-branded docs/plan-fullspektrum-innholdsmotor.md:70 (model brand +
jan-2026 asserted as fact -> no-name/no-month relevance-model phrasing). It was
the only tracked survivor; the rest live in gitignored ROADMAP.md /
.claude/research/ (not shipped, out of honesty scope).

META — added Section 10 model-consistency guard
(scripts/check-model-consistency.mjs): each agents/*.md model: must match every
surface declaration AND the canonical rosters must list all 19 agents.
Permanent non-vacuity self-test + e2e mutation-proven.

Pre-patch sweep confirmed post-feedback-monitor was the sole drifted agent
(89 model rows, 0 other mismatches). test-runner.sh 68/0/0, node --test 94/94.
