feat: add CLI UX flags (--quiet, --verbose, --yes) for ao init

[Shooksie]

Add comprehensive CLI UX flags to control output verbosity:

• --quiet/-q: Suppress progress messages, only show errors and final result
• --verbose/-v: Show detailed step-by-step output during detection and generation
• --yes/-y: Skip all confirmation prompts (non-interactive mode)

Changes:

• Create src/utils/logger.ts with configurable output levels and helper methods
• Update InitOptions interface in src/commands/init.ts with new options
• Add new CLI options to commander in src/index.ts
• Update initCommand to use logger and respect verbosity levels
• Add comprehensive tests for logger module and new init command flags
• Add examples to help text showing new flag usage

The logger provides methods for different output types:

• info, success, warn, error: Normal verbosity messages
• debug, step, detection, generation: Verbose-only messages
• banner, list, result: Output formatting helpers
• isYes(), isQuiet(), isVerbose(): State query methods
