Add GitHub Actions workflow to build and release on tag push

[T0X1Cx]

Follow-up to #21 (per Swizzy's request). Adds a GitHub Actions workflow that builds PS3DumpChecker.exe from source and publishes it as a GitHub Release. Users can trust that a release binary was compiled from the checked-in source by GitHub's own infra, not by a contributor's local machine.

What this does

.github/workflows/build-and-release.yml:

• Triggers on push of v* tags (and manual workflow_dispatch).
• Runs on windows-latest with MSBuild.
• Validates the data files (tools/validate_data.py) before building.
• Builds Release_Embedded against .NET Framework v4.8 (preinstalled on windows-latest; backward-compatible with the csproj's v4.5 source). No targeting pack install needed. The csproj is not modified — the override is a CI-only MSBuild property.
• Refreshes default.hashlist / default.cfg mirrors and their .md5 files in the same 32-uppercase-hex-no-newline format UpdateLatestCompiledVersion.bat produces locally.
• Cleans GAC-fallback junk (mscorlib.dll, norm*.nlp, es/) from the output directory.
• Sanity-checks the embedded patch.bin MD5 in the compiled exe.
• Uploads the artefacts as a workflow artifact AND, on tag pushes, publishes them as a GitHub Release via softprops/action-gh-release@v2.

Release workflow going forward

1. Commit source changes (patch.bin, hashlist.xml, AssemblyInfo bump, changelog entry).
2. git tag v1.0.XXX && git push origin v1.0.XXX.
3. Actions builds and publishes the release automatically.

Verification

Tested on the fork (T0X1Cx/PS3DumpChecker) with a manual workflow_dispatch run and a real tag push — exe compiles green in 32s, embedded patch.bin MD5 matches the expected value, a release is created with all eight artefacts.

Not included here

The compiled binaries in Latest Compiled Version/ are not removed by this PR — that can happen in a separate cleanup PR once you're happy with the workflow, so git blame history for those files stays intact for reviewers.

Summary by CodeRabbit

• New Features
  • Added an automated release workflow for version-tagged and manually triggered builds.
  • Releases now include the compiled application, refreshed configuration and hash data files, and MD5 checksums.
  • Added validation and packaging checks to help ensure release artifacts are complete and consistent.

📝 Walkthrough

Walkthrough

The pull request adds a GitHub Actions workflow for validating, building, packaging, and publishing PS3DumpChecker releases. The workflow supports version tag pushes and manual dispatch.

Changes

Release pipeline

Layer / File(s)	Summary
Build and release workflow .github/workflows/build-and-release.yml	The workflow validates data files, builds PS3DumpChecker in Release_Embedded, regenerates metadata and MD5 files, checks the embedded patch.bin signature, removes fallback files, uploads artifacts, and creates a GitHub Release.

Estimated code review effort: 3 (Moderate) | ~15–30 minutes

Merge Risk: 🟡 Moderate · up to 3324a

The new automation can publish a release whose embedded patch was not actually validated, while mutable workflow dependencies retain release-writing access. Resolve these integrity and supply-chain risks before enabling automated releases.

Thanks — done. Bumped all actions to their current major versions:

• actions/checkout v4 → v7
• microsoft/setup-msbuild v2 → v3
• actions/setup-python v5 → v7
• actions/upload-artifact v4 → v7
• softprops/action-gh-release v2 → v3

Also made the Validate data files step a no-op when tools/validate_data.py isn't in the tree, so this PR is fully mergeable on its own without depending on #21 (once #21 lands the step runs as before).

Verified with a test tag on the fork — 42s green build, release created, all artefacts present.
