fix: address ObsidianReviewBot code review issues

- Fix template literal type issue in notifications.ts by adding
  explicit String() coercion for args.recursive
- Replace Vault.trash() with FileManager.trashFile() to respect
  user's configured deletion preferences (system trash or .trash/)
- Remove unused trash() method from IVaultAdapter and VaultAdapter
- Update tests to reflect new deletion behavior
