refactor(linkedin): absorb authority into strategy + profile canon (S18)

- commands/strategy.md: extend frontmatter with authority triggers; insert
  Step 3.6 Authority Building (signature content map, greatest hits, derivative
  planning, content + network signals, action plan, monthly scorecard); add
  algorithm-signals-reference.md to Reference Files.
- commands/audit.md: Step 5.5 trajectory-review and Step 7 report-block
  trajectory section now route to /linkedin:strategy (the canon); Step 6
  profile-alignment routes to /linkedin:profile (the canon); drop
  trajectory-strategy-adjustments.md + algorithm-signals-reference.md from
  loaded references (canons own them).
- commands/analyze.md: 'If Profile-Content Mismatch' subsection routes to
  /linkedin:profile for the per-section checklist; quick-triage list kept.
- commands/authority.md: removed (absorbed by strategy.md).
- commands/linkedin.md: drop authority table row, merge 'Build authority'
  into AskUser item #10 (Growth strategy & authority), renumber 14-23 to
  13-22, broaden strategy routing trigger keywords, drop standalone
  authority routing rule.
- skills/linkedin-strategy/SKILL.md, skills/linkedin-thought-leadership/SKILL.md,
  CLAUDE.md, README.md: drop /linkedin:authority rows; widen /linkedin:strategy
  descriptions to reflect new scope.

Verification:
- Literal Verify (plan.md:704) exits 1 (expected inversion).
- Corrected predicate (test ! -f && ! grep -rqn …) exits 0 — clean.
- Manifest: commands/strategy.md present; [Aa]uthority match count = 24.
- Hooks: python3 hooks/scripts/compile-hooks.py --check → clean.
- Command count: 25 → 24.
- End-to-end Verification §849 (templates|publish|authority|collab|speaking)
  grep across commands/ agents/ skills/ hooks/ README.md CLAUDE.md → empty.

 ### If Profile-Content Mismatch (360Brew Failure)
 
 **Days 1-3: Profile Audit**
-- [ ] Update headline with 3-4 topic keywords
-- [ ] Rewrite About section with clear expertise
-- [ ] Remove irrelevant Featured content
-- [ ] Check Skills section matches post topics
-- [ ] Request skill endorsements from connections
+
+`/linkedin:profile` is the canonical 360Brew audit — headline scoring, About section structure, Experience impact statements, Featured curation, Skills alignment, content history check, and network signals. Run it for the per-section checklist and the remediation flow.
+
+Quick triage if a full audit can wait:
+- Headline contains 3-4 topic keywords matching content pillars
+- About section's first 3 lines establish specific expertise (before "see more" cutoff)
+- Featured section reflects best work in your pillars
+- Skills align with post topics
