docs(tools): reword the language-dispatch note's two-entries sentence

The Consequences sentence called one of the two table entries "a
SDK_RENDERERS renderer" — circular, since the entry is the renderer mapping.
Reword to "an SDK_RENDERERS entry and a RUN_CODE_FLAVORS entry, plus the
renderer function the former points at" in both languages.

## Consequences
Adding a backend language is two table entries — a `SDK_RENDERERS` renderer and a `RUN_CODE_FLAVORS` entry — plus the renderer itself, with no change to `agent-loop` or the registry structure. The two tables (`SDK_RENDERERS`, `RUN_CODE_FLAVORS`) must stay in step: a language present in one but not the other is a latent inconsistency the `Object.hasOwn` guards turn into a loud failure rather than a wrong-language prompt. The tool layer stays free of any concrete backend dependency, so it lands and is testable on master ahead of the Python protocol and backend; the cost is that a `python` runtime cannot actually be exercised end to end until that backend ships, so this PR's coverage is unit-level (the renderer output and the dispatch/rejection paths) rather than a real Python run.
