v0.6.0-rc86

Fix Linux x86_64 binary build failure (#165)

* Fix compilation error with unstable Rust feature

Replace unstable `is_multiple_of` method with stable modulo operator.
The `unsigned_is_multiple_of` feature is only available in nightly Rust,
but the release workflow uses stable Rust 1.85.0.

This fixes the build failure that prevented v0.6.0-rc85 from publishing
binaries, which was causing "Could not find a suitable binary for linux x86_64"
errors in the Visor system.

* Add Clippy suppression for manual_is_multiple_of lint

The clippy::manual_is_multiple_of lint suggests using is_multiple_of(),
but this method requires unstable Rust features not available in 1.85.0.
We suppress the lint to maintain compatibility with the stable toolchain
used in GitHub Actions.
