Subject: [PATCH] feat(discovery): style golden queries; dimstyle/textstyle
 set_current and drawing_apply_standard join the lean profile
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Five tuning cases for the styles surface (DDIM, the ISO-25 set-current
paraphrase, the one-call drafting-standard paraphrase, the isocp text
style, and the dimstyle counting question) — measured against the live
catalog every one ranks top-1, so no alias vocabulary changed. The
docstring count moves to seventy-one (56 tuning + 15 holdout); the
holdout set is untouched.

Lean decision (spec §8.2): dimstyle_set_current, textstyle_set_current
and drawing_apply_standard join LEAN_TOOL_NAMES (50 -> 53); the seven
authoring/list tools stay full-only and all ten stay in core (no pack
claims them). Pinned by the new profile test in tests/test_styles.py,
written async like the rest of that module (its module-wide asyncio
mark warns on a sync test).
