Portable Web Toolkit v0.4.0

Automatic freshness, live WCAGate integration, and standards-aware public
discovery validation for toolkit-managed Astro + Cloudflare sites.

Highlights

Automatic toolkit freshness: normal toolkit entrypoints perform a
throttled update check, fast-forward only a clean public main checkout,
refresh the unpinned WCAGate main dependency, and report skipped/error
states without overwriting local work.
Live WCAGate bridge: the website accessibility wrapper resolves the
current @imyourboyroy/wcagate engine from the toolkit dependency instead of
maintaining a bundled copy.
Standards-aware Discovery Doctor: bounded sitemap XML, robots, llms,
humans, security.txt, JSON-LD, content-type, REST, and public MCP discovery
validation with same-origin and response-size safety bounds.
Production discovery contract: llms.txt, llms-full.txt,
humans.txt, security.txt, structured content, headers, and homepage
JSON-LD are required by default. Profiles can explicitly relax or extend the
contract; preview/development mode does not require production-only
sitemap/security.txt artifacts.
Wix sourcing doctor: profile-driven public storefront HTML and JSON-LD
harvesting without admin credentials or OAuth.
