* ci: refactor and optimize GitHub Actions workflows\n\n- **Consolidate build processes (`build.yml`, `release.yml`)**: Merged the standalone `.zip` (linux-build) and `.deb` (deb-build) jobs into a single matrix job (`build-and-package` / `build-release`).
This prevents compiling the Rust binaries twice per architecture, effectively cutting the build time in half and saving CI runner minutes.
- **Parallelize and fix Flatpak deployment (`flatter.yml`)**:
- Converted `x86_64` and `aarch64` flatpak jobs to run concurrently via a matrix strategy, removing the sequential bottleneck.
- Resolved an issue where GitHub Pages would only host the `aarch64` repository. Introduced a new `prepare-repo` job that downloads the `.flatpak` bundles from both architectures, merges them into a
single OSTree repository locally, signs it with GPG, and deploys the unified multi-arch repository to GitHub Pages.
- Configured `flatter.yml` to automatically attach the offline `.flatpak` bundles to GitHub Releases when triggered by a release event.
- **Toolchain and cleanup**: Switched hardcoded Rust toolchain version (`1.96.0`) to `stable` across all workflows to prevent manual bumps in the future. Simplified bash scripts and removed redundant
dependency installation steps.
* Extract Copr trigger into a separate job: Copr build now starts immediately in parallel with GitHub Actions builds, eliminating unnecessary waiting time.
* use ubuntu 22.04 to build binaries instead of ubuntu-latest
* fix cache poisoning
* another attemp to fix cache poisoning
* disable cache in setup-rust-toolchain
* use ubuntu-latest
* optimize dependencies in debug profile
* remove --release flag from build.yml and CARGO env vars
* fix flatter names collision
* better flatter key changing
* auto formatting
* add auto updating cargo-sources for dependabot pull requests
* add groups to dependabot.yml
* add github-actions to dependabot
* add ppa deb repo
* add concurrency: gh-pages-deploy
