Refactor most workflows, add cross-rs for cross-compilation, and add new build targets

[7d4d9e33]

Overview

Cleaned up and split GitHub Actions setup, added cross-rs, and introduced a few new build targets.

Changes

• Workflow Split & Cleanup:

  • Replaced pull-request.yml by splitting tests into code-test.yml and lints/formatting into lint-check.yml. Both run on push.
  • Use actions-rust-lang/rustfmt action instead of running rustfmt directly on lint-check.yml for its GitHub problem matcher output in the UI.
  • Moved version extraction into its own reusable workflow (parse-version.yml).
  • Added dedicated pr-*.yml workflows so PR workflow runs don't clutter up regular push runs in GitHub Actions history.

• Artifacts & Releases:

  • build-artifacts.yaml now just uploads workflow artifacts on push/PR instead of creating GitHub releases.
  • Added optional debug profile builds alongside release in build-artifacts.yaml.
  • Added create-release.yml with workflow_dispatch to manually bundle release archives and create a draft release on GitHub when needed.

• Cross-Compilation (cross-rs) & Target Updates:

  • Added Cross.toml and switched compilation steps to use cross. This makes cross-compiling easier in general and avoids header/LLVM conflict issues during MinGW builds on Ubuntu environments.
  • New build targets added:
    • x86_64-pc-windows-gnu (Windows 10+ 64-bit)
    • i686-unknown-linux-musl (Linux 32-bit musl)
    • i586-unknown-linux-musl (Older Linux 32-bit musl, disabled for now due to low demand)
    • i686-pc-windows-gnu (Windows 10+ 32-bit, disabled for now due to boring-sys2 build failures)
  • Existing targets (x86_64-unknown-linux-musl, aarch64-unknown-linux-musl, armv7-unknown-linux-musleabihf) were kept and now build through cross.

Notes

• create-release.yml hasn't been tested on draft release creation yet, but I tested generating the release artifact bundle containing all files.
