docs(specs): clean project-rename-restructure spec - remove all Tauri/desktop references

- Remove Tauri/desktop/frontend implementation details from spec
- Focus exclusively on Python core library with hexagonal architecture
- Update tasks.md: remove Phase 8.2-8.11 (Tauri setup), rewrite Phase 9
- Update design.md: already cleaned in previous commits
- Update requirements.md: already cleaned in previous commits
- Reduce from 59 to 51 task groups across 9 weeks
- Add CLEANUP_COMPLETE.md documenting the cleanup work
- All desktop app content now in separate tauri-desktop-ui spec

This spec now contains ONLY:
- Hexagonal architecture (Ports & Adapters)
- Monorepo structure with apps/core/
- Python library implementation
- Release to PyPI

Desktop app implementation is in .kiro/specs/tauri-desktop-ui/

-## Phase 8.5: Python-Tauri Bridge (Week 8 continuation)
-
-### 8.7 Decide Python Integration Strategy
-**Decision Point**: Choose how Tauri will communicate with Python core library
-
-**Options to evaluate**:
-1. **Subprocess CLI Bridge** (simple, portable)
-   - Tauri spawns Python process
-   - Communication via stdin/stdout JSON
-   - Easy to debug and test
-
-2. **PyO3 Direct Calls** (faster, more complex)
-   - Python embedded in Rust
-   - Direct function calls
-   - Better performance
-
-3. **HTTP Local Server** (flexible, familiar)
-   - Python FastAPI server
-   - Tauri makes HTTP requests
-   - Standard REST patterns
-
-4. **IPC** (Inter-Process Communication)
-   - Named pipes or sockets
-   - Bidirectional communication
-   - More complex setup
-
-- [ ] Evaluate options based on:
-  - [ ] Performance requirements
-  - [ ] Development complexity
-  - [ ] Debugging ease
-  - [ ] Cross-platform compatibility
-- [ ] Document decision and rationale
-- [ ] Proceed with chosen approach
-
-### 8.8 CLI Interface for Subprocess (if chosen)
-**Note**: Only implement if subprocess approach is chosen in 8.7
-
-- [ ] Create `apps/core/src/api/cli.py`
-  - [ ] Add argparse CLI for subprocess calls
-  - [ ] Add `create-profile` command
-  - [ ] Add `generate` command
-  - [ ] Add `list-profiles` command
-  - [ ] Add `delete-profile` command
-  - [ ] Add `validate-samples` command
-  - [ ] Output JSON for Tauri to parse
-  - [ ] Add `if __name__ == '__main__'` block
-  - [ ] Add error handling with JSON error responses
-- [ ] Create `apps/core/tests/api/test_cli.py`
-  - [ ] Test CLI commands
-  - [ ] Test JSON output format
-  - [ ] Test error handling
-  - [ ] Test subprocess invocation
-
-### 8.9 PyO3 Integration (if chosen)
-**Note**: Only implement if PyO3 approach is chosen in 8.7
-
-- [ ] Add PyO3 to Tauri dependencies
-- [ ] Create Python module wrapper
-- [ ] Implement direct function calls
-- [ ] Add error handling
-- [ ] Test integration
-
-### 8.10 HTTP Server (if chosen)
-**Note**: Only implement if HTTP approach is chosen in 8.7
-
-- [ ] Add FastAPI to core dependencies
-- [ ] Create HTTP server wrapper around TTSStudio
-- [ ] Implement REST endpoints
-- [ ] Add CORS for local access
-- [ ] Test server integration
-
-### 8.11 Validation (Bridge Implementation)
-- [ ] Chosen integration approach works
-- [ ] Tauri can call Python successfully
-- [ ] JSON serialization works correctly
-- [ ] Error handling is robust
-- [ ] Performance is acceptable
-- [ ] Cross-platform compatibility verified

-## Phase 9: Release (Week 9)
+**Note**: Desktop app implementation is covered in a separate spec (`.kiro/specs/tauri-desktop-ui/`). This phase focuses on releasing the Python core library v1.0.0.
 
 ### 9.1 Final Testing
 - [ ] Run full test suite: `pytest apps/core/`
 - [ ] Manual testing of Python API
-- [ ] Manual testing of Tauri integration
 - [ ] Performance testing (generation speed)
 - [ ] Memory usage testing
 - [ ] Test on different platforms (macOS, Linux)
