Merge pull request 'fix(manifest): הצהרת legal_predecessor_context ב-manifest (חשיפת הכלי)' (#6) from fix/predecessor-manifest into main

ה-manifest.tools הוא המקור-הקובע לרישום/חשיפת כלים ב-Paperclip — ctx.tools.register
ב-worker.ts נותן רק את ה-handler. בלי הצהרה ב-manifest, הכלי לא נחשף (הלוגים הראו
toolCount=8, בלי legal_predecessor_context). מוסיף את ההצהרה → toolCount=9, הכלי חשוף.

אומת חי: reinstall+restart → logs מראים toolCount:9 + legal_predecessor_context רשום.
(המשך #220; משלים את PR #5.)
