docs(agents): point at the standard instead of restating it

#96: the metadata rules live in section 11 of the
standard, the toolchain in section 1, and the exemptions table records that
that-depends keeps its own tooling; two copies drift. What stays is specific
to this repo: the profile's badge facts, the brand surfaces, the CI
stale-merge-ref gotcha, and the agent-skill pointers.

Two agent-facing gotchas that only AGENTS.md carried move into section 11:
never the keyword "dependency injector", and validate classifier strings
against pypi.org.
