- Prints a configuration table on startup showing each key, its value,
and the source (default / config file / env: VARNAME / flag: --name)
- Lists every commit since the last tag with its parsed type and
the version-bump decision (feat/fix/breaking → patch bump, or ignored)
- Explains the final version choice: highest commit type → next tag
- All verbose output goes to stderr so it never pollutes stdout captures
- Sources tracking wired through config.LoadWithSources and
ApplyEnvWithSources; LoadWithSources uses a two-pass approach to
detect which YAML fields were explicitly set vs defaulted
