Added a packaged markdown-worker sidecar across desktop targets and wired the new runtime through the frontend reader, NoteMD bridge, Tauri packaging, and validation scripts.
Extended the embedded reader/path-mode experience with richer panel refresh, settings synchronization, and markdown rendering flow updates spanning frontend, server, and Godot integration code.
Replaced legacy external docs-publish runbooks with project-owned bilingual GitHub Pages release/rollback guidance and aligned Diataxis/governance references to the new canonical docs.
Added tools/markdown_worker Rust binary and platform packaging paths for Windows, Linux, and macOS.
Introduced src/markdown/MarkdownGateway.ts plus contract/integration coverage for markdown worker runtime selection and server integration.
Updated sidecar build, validation, cleanup, and readiness scripts so the markdown worker is treated as a first-class Tauri sidecar during dev/build/test flows.
Expanded frontend reader and NoteMD integration surfaces:
Switched docs publishing away from the removed external EdgeOne runbook to repo-owned GitHub Pages runbooks:
docs/en/docs_release_and_rollback.md
docs/zh/docs_release_and_rollback.md
Added GitHub Pages preflight/auto-enable logic in .github/workflows/docs-github-pages-publish.yml so docs deployments can self-heal common Pages configuration drift.
Hardened npm-publish.yml with version-existence guarding to keep npm publish idempotent when both tag-push and release events fire for the same version.
Aligned release metadata for 1.6.7 in package/Tauri manifests and refreshed README + Diataxis references to match the new operator workflow.
This release is not just a docs-only cut: it delivers the new markdown worker runtime, expands embedded reader integration, and hardens GitHub Pages plus npm release operations around that rollout.
The compare window remains tightly scoped to v1.6.6..v1.6.7, so the notes above are intended to map directly to the actual shipped delta.
