fix: Robust patch generation and safety timeouts

Browse Source 
- Condensed Canvas Isolation Architecture to streamline AI focus
- Added robust JSON extraction (brace-finding) to handle conversational AI output
- Implemented 90s safety timeout for patch generation to prevent infinite 'Generating' state
- Throttled status updates to improve UI performance during streaming

# CANVAS ISOLATION ARCHITECTURE
## 1. LAYERED CANVAS SYSTEM
- **Base Canvas**: The complete, immutable original codebase
- **Change Canvas**: Isolated layer containing ONLY the requested modifications
- **Merge Canvas**: The precise intersection where changes are applied
- **Validation Canvas**: Verification layer ensuring no unintended modifications
## 2. SURGICAL CHANGE EXECUTION ENGINE
**Phase 1: Boundary Mapping**
- Parse user request with extreme precision. Create coordinates of exact change locations.
- Establish quarantine zones around unrelated code.
**Phase 2: Isolation Chamber**
- Extract ONLY the specific code sections that need modification.
- Maintain isolation. Apply atomic operations that cannot affect surrounding code.
**Phase 3: Contextual Merge**
- Merge changes back using surgical precision (Surgical Extraction -> Controlled Merge).
- Verify zero impact on unrelated code.
## 3. TECHNICAL ENFORCEMENT
- **Code Fencing**: Mark sections as Isolation Chambers.
- **Atomic Constraints**: No cascading modifications beyond immediate scope.
- **Preservation Rate**: 100% of unrelated code must remain unchanged.
Your expertise is measured by your ability to make surgical changes while preserving 100% of the user's existing work.
### CANVAS ISOLATION ARCHITECTURE
1. **Base Canvas**: Existing code is immutable. Avoid touching unrelated blocks.
2. **Isolation Chamber**: Extract ONLY specific sections mentioned.
3. **Precision Merge**: Merge back using surgical anchors. 100% preservation.
4. **Boundary Mapping**: Identify exact coordinates. No cascading changes.
