fix(linkedin-studio): S13 harden calendar — concrete Reschedule snippet + correct camelCase exports

Reschedule action was under-determined vs its sibling actions: prose-only with
no bash snippet, referencing snake_case queue_update_status/queue_add that don't
match the exports (queueUpdateStatus/queueAdd). Replaced with a concrete queueAdd
one-liner using the same id (re-add moves the post in place, no duplicate).
Axes a/b/c/d all PASS post-fix; lint 81/0/0, counts 29/19 unchanged.

+> `state-updater.mjs` BEFORE talk. Class agreed steps 1–2: **stateful queue / publish command** —
+> view + manage the scheduling queue + run the publish action. **NOT post-emitting / feed-draft.**
+> It loads the queue (`queueToday/Upcoming/Overdue/Count/FormatSummary`), renders a 14-day view,
+> offers actions (mark-published / reschedule / cancel / view-draft), and on publish does
+> `queueUpdateStatus('published')` → `updatePostTracking` (state) → a quick first-hour plan that
+> defers the full sprint to `/linkedin:firsthour` + `post-feedback-monitor`. It DISPLAYS hook previews
+> of already-queued drafts → it emits no feed content → the feed-format predicates (hook 110–140,
+> 1,200–1,800 band, no-body-link, buzzwords, rotation) do NOT apply. Axis-a/d heavy.
+
+**WHAT VERIFIED CLEAN (no change).**
+- Queue wiring (axis-a/d): Step 1 (`queueToday/Upcoming/Overdue/Count/FormatSummary`), 3c + Cancel
+  (`queueUpdateStatus`) all match exports in `queue-manager.mjs:41–112` exactly.
+- State-writer (axis-d): `updatePostTracking(stateContent, { postDate, postTopic, hookText, charCount,
+  format })` (`state-updater.mjs:55`) + `writeState` (`:346`) — signature matches Step 3d's call verbatim.
+- Agent wiring (axis-d): `subagent_type: linkedin-studio:post-feedback-monitor` (`:156`) namespaced,
+  agent file present, `Task` in `allowed-tools`. Hand-off to `/linkedin:firsthour` (`:138`) = S12 chain.
+- Graceful degradation (axis-d): missing/corrupt queue → `ensureQueue()` + `readQueue()` try/catch → `[]`
+  (`queue-manager.mjs:12–27`); the "No posts scheduled" branch (`:106–111`) covers the empty case.
+- Algorithm bar (axis-b): the quick first-hour plan (`:151` "15+ engagements in first 60 min", check at
+  30/60) is deliberately light and delegates the full sprint to `/linkedin:firsthour`. No ~70%-reach
+  misattribution (the S12 bug is absent here). SSOT `:81` golden window 60–90 min / first 15–30 min — not
+  contradicted. PASS.
+- Content-quality (axis-c): emits no feed content; the hook "preview" is a truncated display of an
+  existing draft, not a generated hook → feed predicates N/A → PASS.
+
+**THE FIX (1 finding, 1 surgical edit, confined to the Reschedule action).**
+1. [REWORK · axis-a/d] The **Reschedule** action (`:164–170`) was under-determined vs its sibling actions:
+   prose-only with NO bash snippet (unlike Cancel `:177–180` and publish 3c `:116–118`), and it referenced
+   `queue_update_status + queue_add` — **snake_case that does not match the exports** `queueUpdateStatus` /
+   `queueAdd` (`queue-manager.mjs:63,82`). An agent executing it had no concrete command and the names
+   would not resolve if copied literally. Fix: replaced step 3 with a concrete `queueAdd` one-liner using
+   the **same id** (since `queueAdd` filters out the prior id first, `:64`, re-adding moves the post in
+   place — no duplicate), carrying the unchanged fields from the Step-2 entry. Mirrors the Cancel snippet
+   pattern.
+
+**VERIFY.**
+- Re-grepped the final file: no `queue_update_status` / `queue_add` remains; the `queueAdd` reschedule
+  snippet is at `:174`; every `queue*` reference in the file is now camelCase and matches an export.
+- `bash scripts/test-runner.sh` → `Passed: 81 · Failed: 0 · Warnings: 0`, **exit 0**; counts **29/19**
+  unchanged (.md-only edit, node/analytics tests not triggered — unchanged from S12).
+- **One NICE left (anti-gold-plating):** the quick first-hour plan could name the SSOT "first 15–30 min"
+  sub-window, but it deliberately defers to `/linkedin:firsthour`; duplicating it would be scope creep —
+  left.
+- Disposition: **FIXED** (1 edit in `commands/calendar.md`) · 0 deferrals · axes a/b/c/d all PASS post-fix.
