fix(linkedin): close dogfood friction (S14)

Close all 9 friction points from the S13 newsletter dogfood (operator
elected to fix F6-F9 rather than defer):

- F1: namespace all subagent_type calls in newsletter.md to
  linkedin-thought-leadership:<name> (4 sites + canonical note)
- F2: document agent invocation form + reload requirement in CLAUDE.md
  + README.md (reload itself is an operator action)
- F3: add edition-config / edition-delingstekst / edition-HANDOVER
  templates under config/ + wire into Steps 0 and 8 + footer
- F4: reconcile draft path to <serie>/NN-utkast.md (series root)
- F5: de-hardcode series root (explicit arg / LTL_SERIES_ROOT / default)
- F6: config-derive carousel editions (remove Seres CAROUSEL set);
  correct samle comment
- F7: build-html.mjs exits non-zero when zero HTML produced
- F8: guard parseDelingstekst (graceful ENOENT) + correct Step 8 wording
- F9: relocate agents/README.md -> docs/agents-capability-matrix.md

Re-tested: 87/87 plugin tests pass; build-html/build-linkedin behavior
re-verified live. Per-item outcomes logged in dogfood-S13-friction.md.

 **Headline:** the long-form pipeline's deterministic backbone is sound, but its
 **gate layer is currently un-runnable** (F1 + F2). Step 15 must close F1 (a concrete
 one-line-per-call edit) and F2 (reload + a doc note) before the pre-lock persona
 sweep can actually execute — the order is correctly wired, it just cannot fire yet.
+
+---
+
+## Step 15 (S14) — re-test outcomes
+
+All nine friction points were closed (operator elected to fix F6–F9 rather than
+defer). Each was re-tested with a concrete check, not a self-asserted "fixed."
+
+- **F1 — ✅ closed.** All four `Task` call sites in `commands/newsletter.md`
+  (content-repurposer Step 3, fact-checker Step 5, persona-reviewer Steps 6 + 9)
+  now use the namespaced `subagent_type: linkedin-thought-leadership:<name>`, plus a
+  canonical "Agent invocation form (required)" note near the foreground principle.
+  **Check:** `grep -nE 'subagent_type: (fact-checker|persona-reviewer|content-repurposer)' commands/newsletter.md`
+  → zero bare names; `grep -nE 'linkedin-thought-leadership:(fact-checker|persona-reviewer|content-repurposer)'`
+  → all 4 sites namespaced.
+- **F2 — ✅ doc / 🔶 reload.** Documented in `CLAUDE.md` (Agents section: invocation
+  form + reload requirement) and `README.md` (Agent Architecture note). The
+  environmental half — registering a newly-added agent — inherently requires a
+  Claude Code **session reload**; that is an operator action, not a code change.
+  Confirmed F2 persists across `/clear`: `fact-checker`/`persona-reviewer` were
+  still absent from this fresh session's agent registry (only the 15 older agents +
+  README appeared), proving it is a reload gap, not a per-session fluke.
+- **F3 — ✅ closed.** Added `config/edition-config.template.json`,
+  `config/edition-delingstekst.template.md`, `config/edition-HANDOVER.template.md`
+  (formats reverse-engineered from the render scripts, now shipped as reference).
+  Wired into `newsletter.md` Step 0 (HANDOVER), Step 8 (config + delingstekst), and
+  the Reference Files footer. **Check:** all three exist under `config/`;
+  `edition-config.template.json` parses as valid JSON.
+- **F4 — ✅ closed.** Step 3 now writes the canonical `<serie>/NN-utkast.md` in the
+  series root (the exact file Steps 7/8 render), with an explicit "do NOT write
+  `linkedin/<article>.draft.md`" warning. **Check:** no `.draft.md`/`<article>` path
+  refs remain except the intentional anti-pattern warning.
+- **F5 — ✅ closed.** Step 0 resolves a **series root** via an order (explicit path
+  arg → `${LTL_SERIES_ROOT:-…/maskinrommet/serier}/<slug>/` → ask once); maskinrommet
+  is the default, not the only path. The architecture preamble was aligned to match.
+- **F6 — ✅ closed.** `CAROUSEL = new Set(["03","06"])` removed; carousel editions are
+  now config-derived (`config.carousel`, a list of NN strings) via `loadEditionConfig`
+  + `EMPTY_CONFIG` + the new config template. Misleading "samle bygges alltid" comment
+  corrected (build has always been gated on `shareMap.samle`). **Check:** `grep -n
+  CAROUSEL render/build-linkedin.mjs` → none; 20/20 render tests pass (one assertion
+  updated to include the `carousel: []` default).
+- **F7 — ✅ closed.** `build-html.mjs main()` now counts files written, prints
+  `Ingen HTML produsert …` and the CLI guard exits non-zero when zero files are
+  produced (no more silent exit-0 on a typo'd filename). Step 7 wording updated to
+  rely on the exit code AND verify the output file. **Re-tested live:** missing input
+  → exit 1; valid input → exit 0 + `review/NN-utkast.html` written.
+- **F8 — ✅ closed.** `parseDelingstekst()` wrapped in try/catch returning `{}` on
+  ENOENT, matching `loadEditionConfig`'s fail-soft contract; Step 8 wording corrected
+  ("both inputs optional and graceful," not "either file throws"). **Re-tested live:**
+  no delingstekst → `build-linkedin.mjs` exit 0 + `linkedin/01/POST.html` still built.
+- **F9 — ✅ relocated / 🔶 de-register on reload.** `git mv agents/README.md
+  docs/agents-capability-matrix.md` — the only reliable fix, since the file registers
+  by filename (it had no frontmatter yet still appeared as
+  `linkedin-thought-leadership:README`). The stale registration clears on the next
+  Claude Code reload (env, same as F2). **Check:** no README in `agents/`;
+  `docs/agents-capability-matrix.md` present.
+
+### Finding (out of Step 15 scope — recorded, not actioned)
+
+`plan.md` Steps 16, 17, 18 hard-code `agents/README.md` as an explicit `grep` search
+path (plan.md:635, 727, 849). After F9's relocation that path no longer exists. The
+explicit arg is **redundant** with the recursive `agents/` search those greps already
+include, so dropping it (or repointing to `docs/agents-capability-matrix.md`) is
+safe — but `plan.md` is outside Step 15's Files list (Hard Rule 2), so this is logged
+for the operator/those steps rather than edited here. **Action for Steps 16–18:** drop
+the dangling `agents/README.md` arg from their Verify greps, or repoint to the new path.
