1.0.4

Added

Filenames-only mode. Set "filenamesOnly": true in your config, or pass
-f / --filenames-only, and cco skips the summariser and sends only
the list of changed filenames to the final model. The commit message is
cheaper and faster to generate; the trade-off is that the model receives
less evidence, so expect broader, less specific messages. The default
remains false.
The staged diff is still read locally, so ignore and lowPriorityPaths
keep working exactly as before, including both paths of renames and
copies. No diff hunks, file contents or statistics are sent to the model;
filenames are quoted so unusual characters stay inside their list entries.
Everything downstream of the final model is unchanged: formatting rules,
templates, custom instructions, interactive fallbacks, streaming and
cancellation all apply, and Ollama final models still get pinned context
windows with truncation checked on every response.
The final model is told that filenames are its only evidence and must not
invent specific edits or motivations. Verbose output reports that the
summariser was skipped, and library results in this mode contain an empty
summaries array with chunkCount: 0; the summary model is never called
or preloaded.

No action needed. The filenamesOnly option is opt-in and defaults to
false; existing configurations behave identically.
