feat(ci): improve Tauri build pipeline and artifact collection

The CI workflow now installs the required Rust toolchain and uv on
Ubuntu, and passes a no-strip flag into the Tauri build to control
binary stripping behavior per platform. The CI helper script was
updated to collect only expected bundle and signature files, reducing
noise and improving upload correctness. Versioning was aligned across
the Node package and Tauri config for the new release.

- Add platform-specific no_strip handling in the build workflow
- Install Rust toolchain/uv for Ubuntu builds
- Filter collected artifacts by expected extensions and signatures
