Changes:
- Increase command limit from 50 to 100 per project
- Add examples/OPTIMIZE_CONFIG.md with optimization strategies
- Update all documentation references (50 → 100)
- Update tests for new limit
Rationale:
- 50 was too restrictive for projects with many tools (Flutter, etc.)
- Users were unknowingly exceeding limit by listing subcommands
- 100 provides headroom while maintaining security
- New guide teaches wildcard optimization (flutter* vs listing each subcommand)
UI feedback idea: Show command count and optimization suggestions
(tracked for Phase 3 or future enhancement)
