Gavin Mak 05efa68da6 wipe: Add new repo wipe subcommand
This new command allows users to delete projects from the worktree
and from the `.repo` directory. It is a destructive operation.

It handles shared projects by refusing to wipe them unless the
`--force` flag is used. It also checks for uncommitted changes
before wiping.
