Worktree folders should be named after the project directly #27589

Right now the worktree folders are:

~/.t3/worktrees/project-name/t3-27701b14/

but this means that places like shell prompts and IDE (Cursor f.e.) window titles that use the folder name are not recognizable.

Instead, can the folders be something like

~/.t3/worktrees/project-name/project-name-1/

treehouse does the opposite, which is also not ideal:

2     available    ~/.treehouse/project-name-11017d/2/project-name
3     available    ~/.treehouse/project-name-11017d/3/project-name

the folder name should include the project name AND be unique imo.
