fix: adjust default methods array formatting in install script
Analyze CLI codebase for memory leaks, error handling issues, and
resource cleanup problems. Key findings include:
- 4 setInterval calls without cleanup in streaming-orchestrator
- 50+ empty catch blocks silently swallowing errors
- Event listeners never removed from agentService
- Missing dispose methods on key services
- Fire-and-forget async operations with no error handling

Report includes prioritized recommendations for immediate,
short-term, and long-term fixes.
- streaming-orchestrator.ts:
  - Store 4 setInterval references for proper cleanup in startMessageProcessor()
  - Add stopMessageProcessor() to clear all intervals
  - Store event listener handlers in Map for removal on cleanup
  - Add removeServiceListeners() method
  - Add comprehensive dispose() method
  - Fix SIGINT handler to be removable
  - Replace all empty catch blocks with proper error logging
  - Add isDisposed flag to prevent callback execution after cleanup

- chat-manager.ts:
  - Add dispose() method to clean up LRU cache and session data

- agent-service.ts:
  - Replace empty catch blocks with debug logging for generator cleanup
  - Improve dispose() error logging

Fixes critical memory leak issues identified in CODE_QUALITY_ANALYSIS.md
- ai-completion-service.ts: Store cleanup interval, add dispose()
- mem0-provider.ts: Store cleanup interval, add dispose()
- browser-container-manager.ts: Store cleanup interval, add dispose()
- enhanced-tool-router.ts: Store cleanup interval, add dispose()
- agent-router.ts: Store 2 intervals (cleanup + metrics), add dispose()

Updated CODE_QUALITY_ANALYSIS.md with:
- Additional findings from subfolder analysis
- 60+ empty catch blocks identified in nik-cli.ts
- 12+ files with interval leaks documented
- Good examples of proper cleanup patterns
- Tracking of fixes applied
