 * Best-effort `git worktree` shell helpers shared by `release` and `gc`.

 * Both commands detach a worktree the same way (and `gc` additionally

/**
 * `git worktree remove --force` is best-effort: when the path is already
 * pruned the caller still marks the lease released / gc. Returns whether

 *
 * `windowsHide: true` is spelled at each call site rather than shared: the
 * guard (`tests/unit/spawn-windows-hide-guard.test.ts`) resolves a same-file
 * plain-`const` object literal and a spread of it, but not one declared
 * `as const`, frozen, `let`, or imported from another file — measured: both
 * call sites below were reported while the shared constant was `as const`.
