Complete integration tests for two-way sync operations

Browse source 
- Marked all planned integration tests for the two-way sync functionality as completed, ensuring coverage for critical operations such as source property writes, property persistence, instance renames, and lifecycle management.
- Added a new test module specifically for two-way sync, enhancing overall test coverage and reliability of the sync system.
- Updated the change processor to handle file path overrides during instance updates, improving the accuracy of source writes and file management.

//! Integration tests for the two-way sync pipeline (POST /api/write).
//!
//! These tests validate the core operations that allow the plugin's two-way
//! sync to eventually replace `rojo syncback`:
//!
//! 1. Source property writes to disk
//! 2. Non-Source property persistence to meta files
//! 3. Instance rename → file rename
//! 4. ClassName transitions → file extension rename
//! 5. Instance removal with meta file cleanup
//! 6. End-to-end round-trip lifecycle (modify, rename, remove)
//! 7. ProjectNode guard (no project file corruption)
//! 8. Echo suppression (no redundant VFS patches)
//!
//! NOTE: Tests operate on pre-existing instances already in the Rojo tree
//! (from the initial snapshot). Adding new instances via the API writes files
//! to disk but relies on VFS events for tree updates; with echo suppression,
//! those events are suppressed for the paths the API wrote. This is correct
//! behavior — the plugin reconciles its own tree and doesn't need Rojo to
//! re-snapshot what it just sent. Tests that need to interact with the tree
//! (read back IDs, send updates) must use instances from the initial snapshot.
