Drop legacy CI workflows; upload release assets direct to Releases

The old repo shipped three workflows from the pre-fork Tauri version:
build.yml (Vite dist artifact — no longer meaningful since distribution
is via Electrobun), ci.yml (version-sync check referencing the deleted
Casks/skiller.rb), and pages.yml (GitHub Pages for a landing that
targets branch docs and doesn't align with the current product). Remove
them along with their helper scripts.

Refactor release.yml to publish every build artifact straight to the
GitHub Release instead of round-tripping through actions/upload-artifact.
This keeps the release pipeline working even when the account-wide
Actions artifact storage quota is exhausted — the only thing that
matters is the Release itself, which has separate storage.
