chore(meta): realign repo config after directory move

The repo moved to /var/mnt/data/projects/settled-reach (flat layout,
no more /main worktree subdir). Drop the stale autoMemoryDirectory
override (pointed at the old /home path; revert to the native
per-slug memory store) and gitignore .worktrees/, which now holds
per-machine git worktrees under the repo root.
