* 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
* docs: A2A guides, clearer nav for Go and Python
* docs: minor fixes for ADK quickstarts
* revert extra changes
* docs: MOVING files to /tools-custom/
- move files, update links and navigation
- add redirects
