* fix(cli): migrate managed WSL launchers to native exe
* refactor(cli): reconcile managed WSL registrations
* fix(cli): harden WSL registration reconciliation
* fix(cli): serialize and harden WSL CLI registration lifecycle
- Cap per-distro concurrent repairs and add a filesystem lock so two
Orca installs can't race the same distro's launcher/bridge files
- Skip re-adopting a legacy managed launcher when its bridge is user-
owned, avoiding a doomed install retried on every startup
- Track per-distro reconciliation against launcher target + app
version so unchanged registrations aren't re-probed each boot
- Replace command install with a single atomic rename instead of a
move-based backup, closing a window where no orca-ide exists
- Remove the registry invalidate-on-persist-failure path now that
writes are atomic and repair is disk-authoritative
- Add brief negative caching to WSL distro discovery to bound
wsl.exe respawns on persistently broken hosts
- Extract keyed-promise-queue as a shared serialization primitive
