docs: drop stale keep_files / dashboard-config comments

These comments instructed adding adk/** to keep_files, but the repo doesn't use keep_files. Stainless codegen never generates adk/**, agentex/lib/*, or agentex/protocol/* (no codegen header), so those paths are never touched and need no protection; codegen-managed files (pyproject/README/locks) are handled by custom-code 3-way merge instead. The dashboard-config TODO is also done. Corrects the same false claim in adk/README.md.
