Add --verbose flag for detailed logging

[SarthakJain26]

Introduce a --verbose (or --debug) flag to enable detailed logs during command execution. By default, logs should remain minimal, but enabling verbose mode should print additional details (e.g., request payloads, API endpoints).

Acceptance Criteria:

• Add a global --verbose flag.
• Integrate logging library (or cobra hooks) to respect verbosity level.
• Print additional logs only when enabled.
• Add a short section in README about usage.
