Audit this VS Code extension's docs and metadata for release readiness before publishing a new version. Use when bumping the version, writing release notes, or verifying that package.json, the README badge and command table, the CHANGELOG, and the English/Simplified-Chinese NLS files agree with what is actually implemented. Runs typecheck, lint, tests, and a vsce package dry run, then reports release blockers without committing, tagging, or publishing.
