fix(cd): list the .deb assets explicitly so the gui shim is not packaged

[LargeModGames]

Summary

The v0.42.0 release run failed on both Linux builds at the Package Debian (.deb) step:

error: Unable to read asset to add to archive: .../target/x86_64-unknown-linux-gnu/release/spotatui-gui
  cause: No such file or directory (os error 2)

cargo-deb packages every [[bin]] by default, and the spotatui-gui shim from #462 only builds with the gui feature, so the release build never produces it. [package.metadata.deb] now lists its assets explicitly: the spotatui binary and the README. The .deb step has not passed since #462; the two previous release runs failed earlier, at the crates.io publish.

Testing

• cargo metadata --locked passes (no lockfile change)
• cargo build --release --no-default-features --features telemetry,tui, then cargo deb --no-build with the new table: the package holds usr/bin/spotatui, usr/share/doc/spotatui/README and copyright, with Suggests: yt-dlp, ffmpeg intact
• Not verified locally: dpkg-shlibdeps (Arch has no dpkg), so the local package has an empty Depends:. The failed CI job shows it running on the Ubuntu runner, so the released package gets the real dependencies

Additional notes

After merge the v0.42.0 tag is moved to the merge commit and pushed again. The failed run published nothing (no release object, no crates.io upload), so there is nothing to clean up.

The package's long description is the whole README because cargo-deb defaults extended-description to it. Pre-existing, left alone here.

Summary by CodeRabbit

• Bug Fixes
  • Debian packages now install the spotatui executable correctly with appropriate permissions.
  • Package documentation now includes the README in the standard system documentation location.
  • Packaging is more consistent across standard and GUI build configurations.

📝 Walkthrough

Walkthrough

The Debian package metadata now explicitly installs the spotatui release binary and README.md with defined destinations and file modes. This prevents cargo-deb from packaging the GUI binary when it is unavailable.

Changes

Debian packaging

Layer / File(s)	Summary
Explicit Debian asset manifest Cargo.toml	The [package.metadata.deb] section installs target/release/spotatui to usr/bin/ with mode 755 and README.md to usr/share/doc/spotatui/README with mode 644.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: ⚪ Minimal · up to e4655

The Debian package now includes only the CLI binary and README, preventing the unavailable GUI shim from being packaged. The defined paths and permissions match the intended package contents, with no remaining merge-readiness risk identified.
