* fix(python,windows): cross-platform cross-process wheel-install lock The advisory lock that serializes concurrent uv installs into a shared Python wheel-cache dir was gated `#[cfg(unix)]` and used `nix::fcntl::flock` directly, so on Windows there was no cross-process serialization at all. Multiple agents running as services on one Windows host share a single per-user cache dir (`.../Temp/windmill/cache/python_<v>/`); when several jobs install the same package at once their uv processes clobber each other's atomic renames, surfacing as "no .dist-info directory", "RECORD ... cannot find the file specified", and "failed to rename ... os error 2" install failures. Replace the unix-only flock with `fs4`'s cross-platform advisory lock (flock on unix, LockFileEx on windows). Unix behavior is unchanged (same flock syscall, whole-file, released on handle close/process death); Windows now gets a real per-package cross-process lock so co-located agents serialize their installs instead of corrupting the shared cache.

Remaining nix usages need only `user` (plus the workspace-inherited `process`/`signal`).
