[Feature suggestion] Extend commit-msg with auto jira ticket number prefix

[NikitaNazarov1]

Hi there!

Many large teams use project management tools such as Jira/Trello/etc., along with standardized branch and commit naming conventions.
For example most common branch naming pattern looks like:

• $type/$PRJ-$NNN/$ticket_description
  Where:
• $type – ticket type (e.g., task, bug, hotfix, typo)
• $PRJ-$NNN – ticket identifier (e.g., PROJ-1234)
• $ticket_description – short description

Example branch names:

• task/XXX-8765/change_registration_form
• bug/XXX-9012/fix_reimport_worker
• typo/XXX-1234/fix_notification_message_wording
• hotfix/XXX-5678/fix_latest_data_migration

Similarly, commit messages often follow a required format:

• [$PRJ-$NNN] Short commit description

It can be automated via a commit-msg git hook.So, if the branch name contains a ticket identifier (e.g., task/XXX-1234/fix-bug), the hook can automatically prepend [XXX-1234] to the commit message unless it's already present.

I've already implemented this behavior in my gem:

If you think this would be useful here, I'd be happy to open a PR adding similar functionality to overcommit.

Looking forward to your thoughts 🙂
