* feat(mcp): add wildcard pattern support to token UI custom scope
- Add text input fields for wildcard patterns in Custom scope
- Combine wildcard patterns with individual script/flow selections
- Support comma-separated patterns (e.g., f/outline/*,f/docs/*)
- Add help popover explaining pattern syntax with examples
- Backward compatible: empty patterns preserve existing behavior
Closes#7252
* fix(mcp): apply critical code review fixes for wildcard patterns
Apply fixes identified by code-smells agent:
**P0 - Code Duplication (CRITICAL)**
- Extract pattern parsing logic into reusable helper function
- Eliminates duplicate code between scripts and flows processing
- Improves maintainability and consistency
**P1 - Button Validation (CRITICAL)**
- Fix button disable condition to allow pattern-only tokens
- Users can now create tokens with ONLY wildcard patterns
- Resolves Test Scenario #6 from design document
**P2 - State Management (MODERATE)**
- Add $effect to clear patterns when switching scopes
- Prevents stale data from persisting across mode changes
- Improves user experience and data consistency
Changes:
- Added parsePatterns() helper function
- Updated button disable condition with pattern checks
- Added two $effect hooks for state cleanup
- Reduced code duplication by 10 lines
Testing: All edge cases now properly handled including pattern-only tokens
