Add Electron desktop workspace app with Svelte UI and workflows

[JosunLP]

This pull request introduces a major 0.7.0 release with significant new features, improvements, and infrastructure changes. The highlights are the addition of a dedicated Electron desktop app with full CI and release automation, expanded test coverage for the chess engine and evaluation, improved installer scripts, and updated documentation. CI workflows and release pipelines have been refactored to support cross-platform desktop builds and asset publishing.

Major Features and Desktop Integration

• Introduced a new Electron-based desktop app in the desktop/ directory, featuring a Svelte renderer, persistent sessions, local backend launch controls, and native packaging for Linux, macOS, and Windows. Packaged builds support in-app updates and native installers (.deb, .dmg, .msi). [1] [2] [3] [4] [5]
• Updated the README.md and CHANGELOG.md to document the desktop app, new install/uninstall scripts, and all major features added in 0.6.0 and 0.7.0. [1] [2] [3] [4] [5]

CI/CD and Release Automation

• Refactored GitHub Actions workflows to add a cross-platform desktop CI job (ci.yml), desktop release job (release.yml), and dependency review job. Desktop builds are now validated and published for all major platforms, with smoke tests and artifact uploads. [1] [2] [3] [4] [5]
• All Bun setup steps in workflows now pin to bun-version: 1.3.10 for reproducibility. [1] [2] [3] [4]

Engine and Evaluation Test Coverage

• Added perft and evaluation symmetry tests, mate-in-one verification, and transposition-table tests to improve engine reliability and correctness.

Installer and Docs Improvements

• Unified install and uninstall scripts for all platforms (install.sh/uninstall.sh) and updated documentation to reflect the new workflow and platform support. [1] [2]

Version Updates

• Bumped all version metadata (Rust crate, WASM, npm, desktop, docs) to 0.7.0 and promoted the previously unreleased 0.6.0 desktop work to a proper changelog entry. [1] [2] [3]

These changes collectively deliver a robust desktop experience, improved developer workflows, and stronger test coverage for the project.

Erledigt in 913070e, mit anschließendem Cleanup in 1b87df4. desktop/src/backend-url.ts akzeptiert jetzt auch Eingaben wie localhost:8080, weil nur noch echte scheme://-URLs als bereits schematisiert behandelt werden. In src/eval.rs prüft der Bishop-Pair-Test jetzt den exakten Bonus über accumulate_internal(..., false) statt über einen materialverfälschten Vergleich. Validiert mit cargo test eval::tests:: -- --nocapture sowie dem bestehenden Desktop-check-Script; die aktuellen CI-Runs für den PR-Stand sind ebenfalls grün.

Erledigt in d4416a4, mit einer kleinen Klarstellung in f07a47e. Der Desktop akzeptiert für lokal gestartete Backends jetzt nur noch http://-Loopback-URLs, damit Start backend keinen HTTPS-URL gegen einen plain-HTTP-checkai serve startet. Die gemeldete Tabellenstelle in docs/guide/desktop-ui.md habe ich erneut geprüft; im aktuellen Branch sind Header- und Separator-Zeile bereits korrekt mit einfacher führender Pipe vorhanden, daher war dort keine weitere Änderung nötig. Validiert mit cargo fmt --all -- --check und dem bestehenden Desktop-check-Script.

Erledigt in 81612f8, mit Review-Follow-ups bis 068b20d. README und Getting-Started empfehlen jetzt standardmäßig einen gepinnten Release-Download mit SHA-256-Prüfung; die bisherigen Pipe-to-shell-Befehle stehen nur noch als ausdrücklich weniger sicherer Shortcut. Validiert mit git diff --check, erfolgreichem VitePress-Docs-Build und finaler Review/CodeQL-Validierung.
