Three critical fixes in n8n_update_partial_workflow:
- **#665**: Replace incorrect `isNotEmpty`/`isEmpty` operator names with `notEmpty`/`empty`
across validators, sanitizer, docs, and error messages. Add auto-correction in sanitizer.
Unknown operators silently returned false in n8n's execution engine.
- **#659**: Remap numeric `targetInput` values (e.g., "0") to "main" in addConnection.
Relax sourceOutput remapping guard for redundant sourceOutput+sourceIndex combinations.
Also resolves#653 (dangling connections caused by malformed type:"0" connections).
- **#642**: Implement __patch_find_replace for surgical string edits in updateNode.
Previously stored patch objects literally as jsCode, producing [object Object].
Now reads current value, applies find/replace sequentially, writes back the string.

Add transferWorkflow diff operation to move workflows between n8n projects:
- TransferWorkflowOperation type with destinationProjectId field
- WorkflowDiffEngine validates and tracks transfer intent
- Handler calls PUT /workflows/{id}/transfer after update
- N8nApiClient.transferWorkflow() method
- Zod schema validates destinationProjectId is non-empty
- Tool description and documentation updated
- inferIntentFromOperations case for transfer
Also fixes two pre-existing bugs found during review:
- continueOnError path now properly extracts/propagates activation flags
- Debug log in updateConnectionReferences shows correct old name
Based on work by @djakielski in PR #645.
