fix(ci): include update manifests for architecture-specific auto-updates (#611)

* fix(ci): include update manifests in release artifacts

electron-updater requires .yml and .blockmap files to perform
architecture-specific updates on macOS (arm64 vs x64).

Without these files:
- Auto-updater can't detect architecture
- ARM Macs may download Intel builds (run under Rosetta)
- Delta updates don't work

This fix ensures electron-updater can:
- Detect correct architecture (arm64 vs x64)
- Download architecture-specific builds
- Perform efficient delta updates via blockmap files

* fix(ci): copy yml and blockmap files to release assets

The previous commit added yml/blockmap to artifact uploads, but the
'Flatten and validate artifacts' step wasn't copying them to the
release-assets directory.

Without this fix, the manifest files wouldn't be included in the GitHub
release, making the architecture detection fix ineffective.

Thanks to @coderabbitai for catching this!

* fix(ci): add validation for electron-updater manifest files

Adds explicit check that .yml manifest files are present in release
assets. Issues a warning if no manifests found, helping catch cases
where electron-builder fails to generate them.

* fix(ci): separate installer and manifest validation

- Add separate check for installer files (dmg, zip, exe, etc.)
  to prevent releases with only manifest files and no installers
- Change missing yml from warning to error since manifests are
  required for auto-update architecture detection to work
- Improve output formatting to show installers and manifests separately

Addresses review feedback from Auto Claude PR Review.
