Two small follow-ups to #588's review:
* Gemini-code-assist suggested explicitly listing environment variables,
command-line flags, and URLs alongside identifiers/tool-names in the
carve-out clause, since those are exactly the categories an LLM is
likeliest to "helpfully" translate (e.g. `--verbose` or `DEBUG=true`).
Adopting verbatim — the additions are non-controversial and the failure
mode they prevent is real.
* Copilot flagged that the structural test only checked for the `## Language`
heading. A future edit could keep the heading but silently weaken the
section to a generic "respond in the user's language" directive,
dropping the cross-cutting #588 commitment that the model's
`reasoning_content` field — not just the visible reply — follows the
user's language. Add a second structural anchor: assert the section
body mentions `reasoning_content`. This matches the existing rlm test's
"anchor tokens, not prose" convention (the API field name is the
feature contract, not a wording choice).
