WebMCP: a read-only stock lookup

Fictional in-memory data. No purchases, accounts, API keys or model calls. A normal form remains usable without WebMCP.

Checked against the October 27, 2026 community draft. API shape and browser support can change. Enabling a preview API is not proof of an autonomous agent or performance improvement.
