docs(linkedin-studio): Voyage remediation setup — brief + research + plan (Phase 0-3)

Audit-remediation Voyage project authored end-to-end this session:
- brief.md (reviewer PROCEED; validator pass) — full Phase 0-3 scope, phased,
  with success criteria refined by research
- research/01-03 — high-effort external swarm + Gemini (Topic 1); reconciled the
  external bar and corrected several audit feature-premises (no publishable model
  name/date; saves UI-visible not API-pullable; auto-publish possible-not-built;
  9:16 not mandatory; newsletter notifications deduplicated not triple; CLI crash
  = missing npm install, depth-bug latent)
- plan.md (21 steps, 7 sessions, 5 waves; validator pass; A- 88/100) — plan-critic
  REVISE (3 blockers + majors) addressed; scope-guardian ALIGNED; gemini Pass-2
  folded in 2 blind spots (git-history decision; lint stat-grep sequencing)

Execution is future sessions (one wave each) via /trekexecute, /trekreview as the
release gate. Audit report stays local until the article ships.
