refactor(linkedin): merge publish into calendar — reconcile hook refs (S16)

Step 17 of voyage-build (S16 in plan). publish.md absorbed into calendar.md
as an inline action (Mark as Published flow: queue update, state update,
first-hour battle plan) reusing the same queue-manager.mjs + state-updater.mjs
primitives that publish.md called. calendar.md frontmatter triggers extended
with the publish trigger words; quick-routing block jumps straight to the
publish action when the user prompt names it.

All 21 route-refs reconciled across the 9 expected files, with the 9
hook-script refs (5 in session-start.mjs, 2 in posting-reminder.mjs, 1 in
user-prompt-context.mjs, 1 in hooks/prompts/state-update-reminder.md)
rewritten to call /linkedin:calendar so the runtime guidance no longer
points at a dead command. compile-hooks.py --check reports clean (no
type: prompt hook changes touched hooks.json).

Verify (intent: zero stray refs, file gone): exit 0. Literal Verify in
plan.md:727 logged exit 1 (same exit-inverted && pattern as S15 plan.md:635
— logged for plan-pass at Step 21).

Manifest audit: PASS (expected_paths=calendar.md present; must_contain
[Pp]ublish: 17 matches in calendar.md).
