fix: harden release versioning

[web3dev1337]

Summary

• add release consistency helpers that keep package.json, src-tauri/tauri.conf.json, src-tauri/Cargo.toml, and release tags aligned
• harden scripts/tauri/run-tauri-build.js so it syncs versions, clears stale bundle/ output, and verifies installer filenames before upload
• run the release checks in CI, generate release notes on tagged releases, and document the release flow in CLAUDE.md, repo AGENTS.md, and CODEBASE_DOCUMENTATION.md

Test plan

• node --check scripts/tauri/run-tauri-build.js
• node --check scripts/tauri/get-release-version.js
• node --check scripts/tauri/sync-tauri-version.js
• node --check scripts/release/version-utils.js
• node --check scripts/release/check-version-consistency.js
• node --check scripts/release/verify-bundle-version.js
• npm run release:sync-version
• npm run release:check-version
• npm run test:unit -- tests/unit/runTauriBuild.test.js tests/unit/releaseVersioning.test.js --runInBand
