Add GitHub Pages public web distribution

[na399]

Summary

• add a GitHub Pages workflow that validates the existing Rust/Tauri safety boundary, builds the Leptos/WASM application with the /DGX_Lab/ project path, validates generated references, and deploys only tested main artifacts
• add public independence, local-execution, and browser-storage notices while preserving Tauri as the desktop distribution over the same simulator
• document the architectural decision, repository setup, trust and persistence limits, custom-domain migration, and rollback
• refresh Cargo metadata, Make targets, changelog, README, and the checksum manifest

Validation

• workflow YAML parsed successfully
• Cargo manifest parsed successfully
• Pages artifact validator passes a valid /DGX_Lab/ fixture
• Pages artifact validator rejects a root-hosted asset leak
• all created Git blobs match the locally tested Git object hashes
• release manifest contains 207 sorted, unique entries with matching hashes

Deployment behavior

Pull requests build and validate the static distribution but do not publish it. Pushes to main upload and deploy the tested artifact.

After merge

A repository administrator must select GitHub Actions under Settings → Pages once. The next successful main workflow run will then publish the public web edition.

Generate the content pack before verifying the manifest

In a clean GitHub Actions checkout, this command always fails because MANIFEST.sha256 requires dist/DGX_Lab_SLURM_Fundamentals_v1.0.0.dgxlabpack, while /dist/ is ignored and the file is not tracked; neither make check nor static_rust_sanity.py generates it. Consequently every Pages run exits here before the static build, upload, or deployment. Generate the pack first or exclude generated artifacts from manifest verification.
