debug: add comprehensive logging for command registration and sync

- Added _log_registered_commands() to list all commands in tree
- Added logging in __init__ to track command registration
- Enhanced on_ready() sync logging with detailed information
- Shows registered commands before and during sync
- Shows specific guild sync status with command counts
- Added error handling for Forbidden errors (missing permissions)
- Clear warnings when no guilds are synced
