fix(file): require isActive in tool params type, reject multiple files in manage sharing

- FileManageSharingParams.isActive is now required, matching the tool param
  and contract (no compile-time gap that 400s at runtime)
- manage_sharing rejects multiple canonical file IDs instead of silently
  sharing only the first, matching decompress
