feat(linkedin-studio): honest newsletter distribution + profile-SEO + outreach pipeline

Step 17 (Wave 4 S4) of the audit remediation. Applies research/03 §D5 + the
two S2 residual fixes folded in. No new commands/agents (counts stay 27/19).

Newsletter (commands/newsletter.md): new "Distribution channel" section after
Step 10 teaching the HONEST native-newsletter mechanics — bypasses organic feed
ranking via ONE deduplicated notification per subscriber per edition (NOT a
three-touchpoint blast); the mass invite fires once → ~1-2K follower floor
(wait until you can spend it); realistic cold-start 0-100 subs months 1-3;
discloses non-export / no-canonical / no-read-analytics / per-subscriber decay;
explicit below-vs-above-floor decision rule. Sourced to research/03 D5.

Profile (commands/profile.md): new "Profile SEO" section — headline as the
highest-weight search field + a per-section keyword-target table
(headline/about/experience/skills/featured), consistency-over-stuffing rule.

Outreach (commands/outreach.md): Step 8c persists the pipeline board to tracked
state via the new recordOutreachContact mutation (mirrors Step 16's
recordFirstHourPlan): additive last_outreach_date/outreach_active scalars + a
non-R-initial ## Outreach Pipeline section in state-updater.mjs +
config/state-file.template.md + --record-outreach CLI branch. +7 tests
(state-updater 26→33, full hook suite 83→90).

Residual 1 (growth-playbook:216): 9:16 "distribution boost" → 4:5/1:1 guidance
(9:16 mobile-only opt-in; "immersive distribution" = uncorroborated heuristic).
Residual 2 (video-strategy-guide:300): "3-second test determines 70% retention"
→ "front-load value for muted autoplay" (three-second hook is folklore, not a
LinkedIn signal).

Verify: grep checks 1-5 pass; test-runner.sh exit 0 (stat-consistency green);
state-updater 33/33. [skip-docs] — tre-doc + version bump deferred to Step 21.

+### Step 8c: Persist the pipeline to tracked state
+
+The boards above are the working view; the **tracked record** lives in plugin
+state so the pipeline survives across sessions (and shows the same partner the
+next time you run `/linkedin:outreach`). After you add or advance a row, persist
+it with the additive `recordOutreachContact` mutation — the same state pattern
+`/linkedin:firsthour` uses (`recordFirstHourPlan`). It writes a newest-first row
+to a `## Outreach Pipeline` section in `~/.claude/linkedin-studio.local.md` and
+sets `last_outreach_date` / `outreach_active`, **without touching any existing
+field** (a missing field is inserted, never required up front):
+
+```bash
+node "${CLAUDE_PLUGIN_ROOT}/hooks/scripts/state-updater.mjs" --record-outreach \
+  --date "YYYY-MM-DD HH:MM" \
+  --track collab \
+  --partner "@name" \
+  --stage pitched \
+  --next "follow up if no reply" \
+  --due YYYY-MM-DD
+```
+
+- `--track` — `collab` or `speaking` (the row is tagged so one board carries both).
+- `--stage` — `warming` / `pitched` / `in-production` / `delivered` / `follow-up`.
+- `--next` + `--due` — the next action and when it falls due (drives the
+  follow-up surfacing in `/linkedin:calendar` and the Step 10 dashboard).
+
+Re-running with the same partner appends a fresh dated row, so the section is a
+running history of where each contact stands — not a single mutable cell. Read
+the section back at Step 0 of the next outreach session to reconstruct the
+board.
