Auto-generate docs schema and render config reference from JSON Schema

[Copilot]

Documentation needed to render the configuration reference from JSON Schema and keep it synchronized with code comments; CI should generate the schema automatically before building docs.

• Schema-driven reference

  • Render /docs/config/reference from JSON Schema via a reusable MDX component.
  • Persist the generated schema in docs static assets for deterministic builds.

• Schema descriptions

  • Add field-level doc comments across core config structs so schema descriptions are human-readable.

• Docs CI automation

  • Generate schema in the docs workflow before the build (Rust toolchain setup, explicit package run).

Example (schema embed in reference page):

import SchemaReference from '@site/src/components/SchemaReference';

<SchemaReference />

@copilot The job failed because the workflow uses a deprecated version of actions/cache (@v1), which is no longer supported. To fix this, update all references of actions/cache@v1 in your workflow file to actions/cache@v3 or actions/cache@v4.

For example, change:

• name: Cache Cargo
  uses: actions/cache@v1
  with:
  path: ~/.cargo
  key: ${{ matrix.os }}-stable-cargo-v1
  restore-keys: |
  ${{ matrix.os }}-stable-cargo-v1
  to:

• name: Cache Cargo
  uses: actions/cache@v3
  with:
  path: ~/.cargo
  key: ${{ matrix.os }}-stable-cargo-v1
  restore-keys: |
  ${{ matrix.os }}-stable-cargo-v1
  Apply the same replacement for every occurrence in your .github/workflows/rust.yml file. This will resolve the job failure caused by the deprecated action.
