feat(tauri): support self-signed remote HTTPS via server-backed proxy (#333)

## Summary

- add a server-backed HTTPS proxy flow for Tauri remote windows so
self-signed remote HTTPS works with the local CLI TLS assets and desktop
auth/cookie handling
- manage remote proxy sessions through `packages/server` with
per-session bootstrap, local-only cleanup, and explicit session
lifecycle handling
- support the Tauri desktop flow across environments, including packaged
Windows builds, `tauri dev`, and updated Linux/macOS handling for the
new local HTTPS proxy path

## Testing

- `npm run build --workspace @neuralnomads/codenomad`
- `cargo check`
- `npm run build --workspace @codenomad/tauri-app`
- Windows smoke test for concurrent remote proxy bootstrap sessions
- Windows manual validation of packaged Tauri remote connection flow

## Notes

- Windows was validated end-to-end.
- Linux and macOS code paths were updated for the new proxy flow, but
runtime validation on those platforms is still pending.
