Problem or use case

The T3 Code titles generated by default are rather verbose. Like reading through statements or sentences.

This may be to the liking of some, but I would love to be able to provide a prompt with a few concrete examples of how I want T3Code thread title gen to work so that it actually title's threads in the same way that I personally would.

Proposed solution

Allow T3Code to learn from thread title renames by keeping a log of all:
- original names
- new user provided names
- original prompt the was used to generate the original names.

Why this matters

Better UX: This would make thread titles align more with how a user thinks about their work.

Smallest useful scope

Allow users to modify the prompt used for thread title gen the same way you allow custom prompting for source control writing style.

Additional use case: please expose the prompt used for automatic thread-title generation as a user-editable setting.

Ideally, the configured prompt should apply consistently to both initial title generation and Regenerate title, with a Reset to default action. This would let users enforce their preferred style—such as shorter titles, ticket IDs, or a specific language—without modifying T3 Code itself.

A single global prompt override would be a useful smallest scope; per-project overrides could be added later.
