Make ngit non-interactive by default

Implements non-interactive mode as the default behavior for ngit.
Users must now use -i flag for interactive prompts, or provide
all required arguments explicitly. Adds -d flag for sensible
defaults and -f flag for force operations.

Changes:
- CLI interactor infrastructure supports non-interactive mode
- Global flags: -i (interactive), --defaults (use defaults), -f (force)
- ngit init: requires --name or --identifier, supports --defaults
- ngit account: new signup command, login supports non-interactive
- ngit send: validates required fields, supports --defaults
- git-remote-nostr: fixed to prevent interactive prompts during push
- Comprehensive test coverage: 234 unit tests + integration tests
