gsxdsm 7568705244 fix(desktop): boot embedded Postgres in packaged app and ship omp dist (#2106) ...

## Summary

Packaged Fusion desktop Local mode failed after the SQLite→Postgres
cutover:

1. **Embedded Postgres** could not start from `app.asar` — platform
packages resolve `initdb`/`postgres` via `import.meta.url` into the asar
virtual path, and `spawn` fails with `ENOTDIR`.
2. **After Postgres was fixed**, Local mode still fell back to the mode
chooser because `@fusion-plugin-examples/omp-runtime` was never built
into `dist/` (dashboard imports it from `runtime-provider-probes.ts`).

This PR makes packaged Local mode boot embedded Postgres reliably and
keep the dashboard shell up.

### Changes

- **CJS bootstrap** (`main-bootstrap.cjs`) as Electron `main`: patches
`child_process.spawn` / `fs.promises.stat|chmod` before the ESM main
loads so asar binary paths rewrite to real files.
- **Materialize** the full native PG install (`bin` + `lib` + `share`)
under `~/.fusion/embedded-postgres/runtime-bin/<plat-arch>/`.
- **electron-builder**: full `asarUnpack` of embedded-postgres packages;
allowlist PG deps and `@fusion-plugin-examples/**/*` (+ plugin-sdk / ACP
SDK).
- **Build** `fusion-plugin-omp-runtime` with the other dashboard-static
runtime plugins; export `DASHBOARD_RUNTIME_PLUGIN_PACKAGES` for tests.
- Unit coverage for asar path rewrite, packaging allowlists, and omp
build inclusion.

## Test plan

- [x] `pnpm --filter @fusion/core test:embedded-postgres` (23/23)
- [x] Desktop packaging unit tests (`build-bundling`,
`electron-builder-config`)
- [x] Packaged macOS `Fusion.app` Local mode:
  - [x] `embedded postgres: ready on port … (database "fusion")`
  - [x] `desktopMode` stays `"local"` (no chooser fallback)
- [x] `GET /api/health` → `status: ok`, `database.healthy: true`,
`engine.available: true`
- [x] Linux embedded binary lifecycle smoke (Docker aarch64,
`@embedded-postgres/linux-arm64`) — initdb/start/persist/restart
- [ ] CI release desktop jobs (macOS/Linux) when this lands
- [ ] Windows packaged desktop Local + PG (separate agent / host)

## Verification notes

| Platform | Embedded Postgres | Packaged Local shell |
|----------|-------------------|----------------------|
| macOS | Working | Working after this PR |
| Linux | Native binary smoke pass | Full AppImage not built on this
host |
| Windows | Out of scope here | Separate verification |

## Summary by CodeRabbit

* **Bug Fixes**
* Improved embedded PostgreSQL reliability in Electron-packaged apps by
rewriting bundled `app.asar` binary paths to their unpacked/materialized
locations.
* Ensured embedded PostgreSQL runtime binaries resolve correctly across
platforms/architectures, with best-effort executable permissions and
macOS dylib link normalization.

* **Packaging**
* Updated the desktop Electron entry to use a bootstrap module for
embedded PostgreSQL binary resolution.
* Expanded Electron Builder inclusion and asar-unpack rules for
embedded-postgres and related packages, plus required runtime plugin/sdk
assets.

* **Tests**
* Updated and added checks to match the new packaging and plugin/runtime
expectations.
