v2.8.1

This is a small maintenance release focused on the GUI (mp3rgui) and on closing a gap in CI coverage.

GUI fixes (Windows) — thanks to @valipod

Both issues were reported and fixed by @valipod (Valentin Dumitru) in #198 — thank you!

• Show the full file path in the file table instead of only the filename, so files coming from deep or nested folder structures can be told apart. The full path is also shown on hover. (#196)
• Fix "Open file location" for paths containing spaces. It previously opened the Documents folder; it now correctly reveals the selected file in Explorer. (#197)

CI

• Build and lint mp3rgui across Linux, macOS and Windows on every PR (#199). The GUI is a standalone crate outside the root cargo build, so its platform-specific code — including the Windows "reveal in Explorer" path fixed above — was never compiled by CI and only got built at release time. This release adds a dedicated CI job that builds and clippy-checks the GUI on all three platforms, so such regressions are now caught in pull requests instead of at release.

Other changes

• docs: refresh README / COMPARISON, add brand banner and GUI screenshot
• packaging: winget / AUR / MacPorts manifest updates
