fix(deploy): rebuild the docs index for the new guides, and trigger on every path the edge bundle imports

The Pages Functions bundle imports src/mcp, src/scrapers/twitter/http and two
files under api/, but the deploy workflow did not watch any of them, so a change
to a tool definition or a GraphQL query ID shipped nothing and the edge kept
running the previous bundle.

The retrieval index feeds both the Ask page and the MCP server's documentation
search and resources, so a new guide that is not in it is invisible to every
agent that connects. Rebuilt: 5208 chunks, including the hosted MCP guide.
