FIX: Improve startup flow error handling and correctness

CRITICAL: Library sourcing error handling
- launcher.sh lines 21-25: Added error checks for all source commands
- Each library now reports if it fails to load
- Script exits with message instead of silent failure

MEDIUM: init_directories error checking
- launcher.sh lines 630-631: Added error handling for mkdir -p
- Script now reports if directory creation fails
- Better user feedback on initialization errors

HIGH: Stderr redirect cleanup
- run.sh line 14: Removed misplaced 2>/dev/null after closing bracket
- launcher.sh lines 678, 694: Reordered redirects for clarity
  (read ... </dev/tty 2>/dev/null instead of 2>/dev/null </dev/tty)

REASON: Improves startup robustness by catching initialization failures
early and providing helpful error messages instead of silent failures.
