Complete Phase 1.8: CLI Framework (Basic Commands)

Implements the complete CLI interface using Typer with Rich console output.

Commands implemented:
- forge init: Creates config.yaml from config.example.yaml
- forge generate: Generates logs from scenario files with validation and error handling
- forge version: Shows version information

Features:
- Schema validation with clear error messages
- Proper exit codes (0=success, 1=input error, 2=schema validation, 21=generation error, 130=SIGINT)
- Rich console formatting with progress messages and file listings
- Command-line flags: --output, --config, --verbose, --force
- Timestamped output directories for each generation run

Bug fixes:
- Fixed StateManager to allow PID 4 as system process parent (Windows System process)
- Fixed session lookup: get_sessions_for_user returns list[ActiveSession], not dict
- Fixed persona handling: Phase 1 uses string persona names, not Persona objects
- Fixed CLI exit handling: use return instead of raise typer.Exit(EXIT_SUCCESS)

Testing:
- All three test scenarios generate successfully (minimal, baseline-only, attack)
- GROUND_TRUTH.md generated only for attack scenarios
- Cross-log consistency maintained (LogonIDs, PIDs, timestamps)
