fix(linkedin-studio): Oppgave 1 fix-pass — clipboard heredoc + report refs + calendar queue-felter [skip-docs]

Primær-sti-fixer fra cold-review:
- clipboard (10 cmds): printf '%s' '<text>' → quoted heredoc (apostrof/%/$/backtick
  korrumperte stdin); «Copied» betinget på COPIED, FAILED → be om manuell kopi
- report.md: heatmap-gren pekte til ikke-eksisterende «Step 6c» → «Step 2c»;
  Step 8b export skriver .md → la til Write i allowed-tools
- calendar.md: Step 1 emitter ENTRY RECORDS (id/draft_path/character_count) fra
  returnerte entry-objekter; publish + reschedule resolver id derfra
  (queueFormatSummary droppet feltene → handlingene var brutt)

test-runner: 138 passed / 0 failed.

 - Save to `${LINKEDIN_STUDIO_DATA:-$HOME/.claude/linkedin-studio}/drafts/multiplatform/[platform]-[slug].md`
 - Auto-copy the adapted content to clipboard silently:
 ```bash
-printf '%s' '<ADAPTED_CONTENT>' | node ${CLAUDE_PLUGIN_ROOT}/hooks/scripts/clipboard-helper.mjs
+node ${CLAUDE_PLUGIN_ROOT}/hooks/scripts/clipboard-helper.mjs <<'__LINKEDIN_CLIP_EOF__'

 ```
-- Present the content and confirm: "Copied to clipboard."
+- Substitute `<ADAPTED_CONTENT>` with the exact adapted text between the heredoc markers (a quoted heredoc keeps apostrophes, `%`, `$`, and backticks literal). Present the content, and only if the helper prints `COPIED`, confirm: "Copied to clipboard." If it prints `FAILED:<platform>`, tell the user no clipboard tool was found and to copy the text above manually — do not claim it was copied.
