feat(linkedin-studio): S14 — journey layer (create/measure front-doors + 5-journey router), v4.1.0

14a's cold command-rationalization found ZERO redundancy across the 27 commands
(no defensible merge/cut), so the operator reframed S14 from "merge/cut" to
"add a journey layer over the kept atomics".

- Add /linkedin:create + /linkedin:measure — delegate-only guided front-doors
  (Read/Glob/AskUserQuestion only; route to the command that owns the work)
- Re-tier commands/linkedin.md into 5 journeys (Start/Create/Engage/Measure/Grow);
  onboarding/strategy elevated as Start/Grow front-doors; Engage = calendar+firsthour tier
- 14a honesty nits: router now lists firsthour; calendar cross-links to firsthour;
  competitive confirmed UNGATED (the claimed 1K-gating inconsistency was unfounded)
- Lockstep: EXPECT_COMMANDS 27->29, v4.0.0->4.1.0 across plugin.json / README badges /
  plugin+root CLAUDE.md / README / CHANGELOG; new README commands-badge lint guard
- 14a deliverable corrected: multiplatform entry added (26/27 -> 27/27), header counts,
  competitive nit withdrawn
- Independent /trekreview (2 Opus reviewers) raised 3 MAJORs (stale commands badge,
  router competitive self-contradiction, STATE.md count) — ALL remediated in-session;
  verdict ALLOW

Gate: test-runner.sh 74/0/0; node --test 98/98; commands=29; v4.1.0 consistent.
Additive/minor — no command removed/renamed/behavior-changed; reload registers create+measure.
