[006] Configure automated semantic versioning

[konard]

Summary

• Documents package.json as the single source of truth for package, app, and release metadata during the foundation phase.
• Adds src/foundation/release-metadata.mjs and scripts/validate-release.mjs to enforce stable semantic version syntax and metadata consistency.
• Adds a release validation workflow that runs on pull requests and issue/main pushes without any publishing step, keeping unreviewed PR code from releasing packages.
• Wires release validation into the local pre-commit hook, foundation validation, README, and build guide.
• Removes the generated placeholder .gitkeep from the issue branch.

Reproduction / Verification

Before this work, there was no documented version source of truth or CI check for release metadata. test/release-metadata.test.mjs now fails if the metadata contract, stable semantic version rules, or no-publish PR workflow guarantee are removed.

Tests

• npm test
• npm run validate:foundation
• npm run validate:release
• npm run decompose:dry-run
• git diff --check

Fixes #35
