The live API exposes template browse groups, but the CLI has no group flag and labels grouped results as brands. Add templates list --group, describe --group-by group, and render browse-group counts with the correct heading and nouns. Regenerate the spec, request/response types and command reference from app main 9bf2e01f14d8260bdde0825e901a05497b66c70c; the contract also carries the six new email categories.

SDK 13 already forwards the query object unchanged, so this keeps the released registry dependency. Count-response types follow the CLI's canonical generated contract. No version bump or package publication is included. Companions: SDK #78 and docs #347, from the same source. The read-only live spec matches it exactly (SHA256 0e9c6bcbffe4d846141be275a6675085709e51a2c979727cadba76557d373185).

Validation: the new group flag/output regression failed before implementation. TypeScript, exact-file Biome, 16 focused command/parity tests, a final 3-test group-output rerun, generated command freshness, cross-repository OpenAPI freshness and git diff --check pass. No live API mutation was performed.

Confidence Score: 5/5

The PR appears safe to merge; no actionable issues were found.
