## Summary
- **Windows CI:** run the embedded Postgres smoke as non-admin
`fusion-pg` (with profile prewarm) so elevated `windows-latest` runners
stop failing with PostgreSQL’s admin-token refusal. Packaging still runs
as the job user.
- **Linux AppImage:** add a packaging content verifier for
`main-bootstrap`, `@embedded-postgres` natives, and `omp-runtime` dist
entrypoints; wire it into `release.yml`, `test-release.yml`, and the
advisory **Desktop packaging** PR lane (after `electron-builder --dir`).
- Fix eslint `no-undef` on bare `URL` in the verifier script (was red on
#2131).
## Context
Desktop packaging on Ubuntu was mostly green; Windows desktop builds and
the AppImage packaging PR (#2131 lint) were the remaining red paths. The
win-pg-diag pivot (run smoke as non-admin) proved green on CI; this
ports that approach without removing main’s elevated-token product path
for end-user “Run as administrator” cases (smoke simply does not take
that path when the process is non-admin).
## Test plan
- [x] `pnpm --filter @fusion/desktop exec vitest run
src/__tests__/release-workflow.test.ts`
- [x] `pnpm exec eslint scripts/verify-desktop-linux-pg-packaging.mjs`
- [ ] Desktop packaging workflow on this PR
- [ ] Desktop Windows Build (workflow_dispatch)
- [ ] Confirm #2131 supersession if this lands the same AppImage checks

## Summary by CodeRabbit
* **Bug Fixes**
* Strengthened Linux desktop AppImage validation to confirm embedded
PostgreSQL artifacts, required binaries, symlink hydration, and the
expected app entrypoints are present after packaging.
* Improved Windows embedded PostgreSQL smoke testing by running under a
non-administrator helper user with a prewarmed profile environment.
* **Tests**
* Added automated packaging/release workflow verification steps (Linux
and Windows) to catch embedded PostgreSQL content regressions earlier,
including during artifact build and release verification.
