Add two new exception classes:
- TaskConfigurationError(TaskWarriorError): environment/config errors
  (binary not found, taskrc file missing or unreadable)
- TaskOperationError(TaskWarriorError): write operation failures on
  existing tasks (delete, purge, done, start, stop, annotate)

Export all 6 exceptions from __init__.py (they were not public before)

Semantic fixes:
- TaskValidationError → TaskConfigurationError for 'binary not found'
- TaskValidationError → TaskWarriorError for JSON parse errors on CLI responses
- TaskNotFound → TaskOperationError for delete/purge/done/start/stop/annotate
- TaskNotFound → TaskWarriorError for JSON errors in get_recurring_instances
- TaskWarriorError → TaskNotFound when get_task returns nonzero returncode
- TaskValidationError → TaskWarriorError in modify_task (generic CLI failure)
- TaskWarriorError → TaskValidationError in ContextService._validate_name
- TaskWarriorError → TaskConfigurationError in UdaRegistry for missing taskrc
- RuntimeError → TaskWarriorError in add_task fallback path

Missing coverage added:
- OSError/SubprocessError wrapped in TaskWarriorError in run_task_command
- try/except json.JSONDecodeError added in get_recurring_task (only method missing it)
- FileNotFoundError/PermissionError/OSError handled in ConfigStore._extract_taskrc_config
- Double ValueError fixed in parse_taskwarrior_date (fallback could raise uncaught)

Update Raises: docstrings in main.py to reflect new exception types.
Update tests to match new exception behaviors.

Replace the taskchampion-py-based SyncLocal backend with a direct call to
the TaskWarrior CLI's built-in 'task sync' command.

Removed:
- taskchampion-py dependency from pyproject.toml
- src/taskwarrior/sync_backends/ (sync_local.py, sync_protocol.py, factory.py)
- champion.py (exploratory root-level script)
- tests: test_sync_local, test_sync_factory, test_sync_integration,
         test_sync_disabled_facade (all taskchampion-specific)

Changed:
- TaskWarriorAdapter: _sync field replaced by _sync_configured bool;
  synchronize() runs run_task_command(['sync']), raises TaskSyncError
  if not configured or if task sync exits non-zero
- TaskWarrior (façade): synchronize() now calls self.adapter.synchronize()
  and is no longer a no-op; docstring updated
- CHANGELOG: 1.2.0 entry updated (sync section rewritten)
- README: sync table updated, temporary notice removed

Added:
- tests/unit/test_adapter_sync.py — 9 tests covering is_sync_configured()
  and synchronize() (not-configured, success, stderr/stdout errors)
- test_main_sync.py rewritten: delegates to adapter, propagates TaskSyncError

164 tests passing.

- Delete TaskWarrior.task_cmd and TaskWarrior.taskrc_file storage (lines 92-93)
- These values already exist in TaskWarriorAdapter and ConfigStore (single source of truth)
- Update get_info() to delegate to adapter.task_cmd and config_store.taskrc_path
- Add public taskrc_path property to ConfigStore for clean access
- All 164 tests pass
