when resolving `import.meta.url`, so paths with encoded characters and Windows
drive prefixes compare correctly with `process.argv[1]`.

embedUpdateInfoInAppImage and generateZsyncFile; when either fails and
process.env.CI is set, set a non-zero process exit code. Only attempt zsync
generation after embedding succeeds.

Update latest-linux.yml after embedding the AppImage.
electron-builder generates latest-linux.yml before embedUpdateInfoInAppImage modifies the AppImage bytes. The metadata can therefore contain a stale SHA-512 value, which can cause Electron auto-updates to reject the AppImage. Add a post-embedding step that recomputes the SHA-512 entry before the metadata is uploaded.

Summary
Closes #1021
This PR adds support for AppImage update information and
.zsyncdelta updates on Linux.Problem
Currently, updating Recordly on Linux requires downloading the entire ~200MB AppImage binary on every new release. Furthermore, Linux AppImage managers like
AppImageUpdate,AppImageLauncher,AM, andAppManagercannot perform delta updates or check release channels because the AppImage runtime lacks embedded update information.Solution
scripts/embed-appimage-updateinfo.mjsthat dynamically parses the AppImage ELF headers and injects standard GitHub release update information (gh-releases-zsync|webadderallorg|Recordly|latest|<filename>.AppImage.zsync) into the.upd_infoELF section..zsync): Automatically generates the.zsynccontrol file usingzsyncmakefor differential downloading.zsyncin.github/workflows/release.ymlandbuild.yml.release/*.zsyncin the uploaded Linux release assets and checksum manifests (scripts/write-release-checksums.mjs).webadderallorginelectron-builder.json5.Testing
