feat: add autobuild version support and unify version update scripts

- Support autobuild version with timestamp (e.g. 2.3.0+autobuild.2506021530) via `pnpm release-version autobuild`
- Sync version to package.json, Cargo.toml, tauri.conf.json
- Improve version regex to support build metadata
- Remove old release_version.mjs and release-alpha_version.mjs, use release-version.mjs for all
- Fix script path issues
