Apply saved config

When a configuration is already saved, --apply-config regenerates the project from it in one shot — no prompts, no selection flags. It rewrites the LICENSE from the saved license and copyright fields, records the identifier in every manifest present, and, when the config opted into them, re-stamps the source-file headers in the saved style.

This is the complement of saving: one run records your choice, the other replays it — handy for restoring a project's license state in CI or after a fresh checkout. If no configuration is found, it reports the problem and exits non-zero rather than generating something you didn't ask for. Add --dry-run to preview the regeneration without writing.
