* Replace google.github.io/adk-docs URLs and /adk-docs/ paths with adk.dev
Migrate all hardcoded documentation references to use the new custom
domain. Update root-relative links to remove the /adk-docs/ subpath
prefix since the site will be served from the root of adk.dev.
* Additional fixes
* Adds the Google Developer Knowledge MCP server.
* Edits for formatting and consistency
* Update StreamableHTTPConnectionParams across integration docs
