Release Foxglove extension as installable .foxe again

The release workflow's build-foxglove job had been zipping the raw dist/
folder into cloudini-foxglove-<version>.zip, which is not an installable
Foxglove extension. Use the existing `npm run package` script so CI emits
a proper .foxe (via foxglove-extension package) and attach that to releases.

Also fix the foxglove extension build, which was broken by the typescript
6.0.3 bump: silence the now-fatal moduleResolution deprecation and give
new Uint8Array an explicit length argument.
