Branch name prefixes

[KieranP]

What problem does this solve?

Our convention at work is to have all branches prefixes by the engineers first name. e.g. kieran/fix-bug-123

Currently, I have to type this manually each time I create a new worktree.

Proposed solution

It would be nice if there was support for both a global branch prefix, and per project branch prefixes.
