feat(workflow-util): add frontmatter markdown parser and validator

Phase 1 of RFC #351 — define AgentFrontmatter type, parseFrontmatterMarkdown() and validateFrontmatter() with 45 tests. - Built-in minimal YAML parser (no new deps) - Never throws on malformed input — degrades gracefully - All fields use T | null (no optional properties) Refs #351
Merge pull request 'chore: internalize unused exports across all packages' (#283 ) from chore/audit-exports-cleanup into main

+Hello and welcome! This folder has been automatically generated by `@changesets/cli`, a build tool that works
+with multi-package repos, or single-package repos to help you version and publish your code. You can
+find the full documentation for it [in our repository](https://github.com/changesets/changesets).
+
+We have a quick list of common questions to get you started engaging with this project in
+[our documentation](https://github.com/changesets/changesets/blob/main/docs/common-questions.md).

-### Publishing to Gitea npm Registry
+### Version Management & Publishing

-All public `@uncaged/*` packages are published to the Gitea npm registry at `git.shazhou.work`. Workflow workspaces consume packages from this registry via `bunfig.toml`.
+All public `@uncaged/*` packages are published to **npmjs.org** via `@changesets/cli` with **fixed mode** (all packages share the same version number). `workflow-dashboard` is private and excluded.

 ```bash
-# Publish all packages (bun pm pack resolves workspace:* → actual versions)
-bun run publish:gitea
+# 1. After making changes, add a changeset describing the change
+bun changeset

-# Dry run — see what would be published
-bun run publish:gitea:dry
+# 2. Before release, bump all package versions + generate CHANGELOGs
+bun version
+
+# 3. Build, test, and publish to npmjs
+bun release
 ```

-Prerequisites: `.npmrc` in monorepo root with Gitea auth token (`//git.shazhou.work/api/packages/shazhou/npm/:_authToken=<token>`).
+- `workspace:^` dependencies resolve to `^x.y.z` on publish
+- Changesets config: `.changeset/config.json` (fixed mode, public access)
+- Each package has auto-generated `CHANGELOG.md`

-### Workflow Workspace Setup
+### Consuming @uncaged/* Packages

-External workflow repos (e.g. `xingyue-workflows`) use the Gitea registry for `@uncaged/*` packages. Add a `bunfig.toml`:
-
-```toml
-[install.scopes]
-"@uncaged" = "https://git.shazhou.work/api/packages/shazhou/npm/"
-```
-
-Then `bun install` resolves `@uncaged/*` from Gitea, all other packages from npmjs.
-
-### Cross-repo Development (bun link)
-
-Alternative for development against un-published local changes:
-
-```bash
-bun run link            # Register all packages (from monorepo root)
-bun run link:consume    # Link into CWD's project (⚠️ don't bun install after)
-bun run link:unlink     # Restore original deps
-```
+External workflow repos just `bun install` — packages come from npmjs like any other dependency. No special registry config needed.

 ### End-to-end: Monorepo → Registry → Workspace → Bundle

-The recommended development flow for building workflows:
-
 ```
 workflow/ (monorepo)           — engine, runtime, templates, agents
-  │  bun run publish:gitea     — auto topo-sort, bun pm pack → npm publish
+  │  bun release               — build + test + changeset publish
  ▼
-git.shazhou.work npm registry  — @uncaged/* scoped packages
-  │  bun install               — via bunfig.toml scoped registry
+npmjs.org                      — @uncaged/* scoped packages (public)
+  │  bun install
  ▼
-my-workflows/ (workspace)     — bunfig.toml + normal package.json
+my-workflows/ (workspace)     — normal package.json
  │  bun run build:develop     — bun build → single .esm.js
  ▼
 uncaged-workflow workflow add  — register bundle locally
 uncaged-workflow run           — execute workflow
 ```

-1. **Monorepo changes** → `bun run publish:gitea` (packages auto-discovered from `packages/*/`, topologically sorted, `workspace:*` resolved to real versions)
-2. **Workspace** → `bun install` fetches latest from Gitea, `bun install` is safe to run anytime
+1. **Monorepo changes** → `bun changeset` (describe change) → `bun version` (bump) → `bun release` (publish)
+2. **Workspace** → `bun install` fetches latest from npmjs
 3. **Build** → produces single-file ESM bundle with `@uncaged/*` as externals
 4. **Register & Run** → `uncaged-workflow workflow add <name> <bundle>` then `uncaged-workflow run <name>`

 ### Bundle import restrictions

 The bundle validator only allows these import specifiers:
 - Node built-ins (\`node:fs\`, \`node:path\`, etc.)
- \`@uncaged/workflow-*\` packages

-Third-party packages (**including zod**) must be bundled into the \`.esm.js\` file, not left as external imports. When using \`bun build\`, only mark \`@uncaged/*\` as external.
+All other dependencies — including \`@uncaged/workflow-*\` packages, zod, and any third-party code — must be bundled into the \`.esm.js\` file. Bundles are fully self-contained: same Node/Bun version = same behavior.
