Make worktree creation optional

The feature, motivation and pitch

Most of my project need a worktree per session, but in some exceptions i have projects there most of the code base is informational and i only need sessions to edit individual files, while reading the latest states on all other files (e.g. legal texts).

For these cases i'd need all sessions always to read the latest states on all files edited by all sessions, and i handle git git pushing independently.

Would be great to have an option to disable worktree creation per project.
