docs(docker): warn that a plain agent-image rebuild keeps stale CLIs

The CLIs live in one `RUN npm install -g` layer, so rebuilding without
--no-cache re-uses it and freezes them at the versions the image was FIRST
built with. Editing the Dockerfile does not help when the edit lands below
that line: the npm layer stays cached and only the new step runs.

That is not hypothetical. Adding the Antigravity step (which appends below
the npm line) produced a "successful" rebuild that silently kept a stale
@openai/codex@0.144.6 whose aliased platform binary had never installed, so
every codex docker case died with "Missing optional dependency
@openai/codex-linux-x64" while the build reported success. A --no-cache
rebuild fixed codex and also un-froze claude, gemini and opencode.

Documents the failure, makes --no-cache the recommended invocation in both
the guide and the CLAUDE.md quick-reference row, and adds a verify command
that actually executes each CLI, since a zero exit code only proves the
layers ran.

No changeset: docs-only, rides the next release.
