Worktree-specific config

[hakoerber]

A TOML in the root of a worktree like this:

persistent_branches = [
    "master",
    "develop",
]

[track]
default = true
default_remote = "origin"
default_prefix = "myprefix"

persistent_branches will be used for:

• grm wt clean will never clean up these branches
• grm wt clean will clean branches that are merged into these persistent branches
• grm wt delete does not require --force if the branch is merged into these persistent branches

default_track will automatically add a tracking branch on grm wt add. By default, it will track origin/{branchname}. The remote can be configured with default_track_remote, and a prefix can be given with default_track_remote. Prefix is used like {remote}/{prefix}/{branchname}
