SDF is the only text renderer now — the stroke path and its LOD ladder are gone, and the remaining text kinds render as SDF glyph quads too. - ATTDEF / ATTRIB: carry a GlyphRun so single-line attribute text renders as SDF (multi-line already did via layout_mtext). Tolerance / complex-linetype text already SDF. - Remove `sdf_text_enabled()` (the OCS_TEXT_SDF flag / kill switch) and take the SDF path unconditionally everywhere: tessellate Text arm (per-group by GlyphRun presence), hit_test fallbacks, render gather, complex_lt, table, mleader. - Delete the text LOD ladder: tess.rs baseline/greek block and the block_cache greek/baseline path (emit_greeked_text / emit_text_baseline), plus the now-dead helpers text_baseline_points / text_greek_obb_tris / text_obb_corners_native / mtext_line_count and the LocalWire text_height_local / text_obb_local fields. All text is crisp at every zoom; text entities are exempt from the sub-pixel stub cull. - Fix a latent bug: block-internal SDF text was culled because its LocalWire aabb_local was [0,0,0,0] (no points) — fold the glyph-quad extent into aabb_local and exempt text_verts-carrying wires from the sub-pixel cull. - Clear the pre-existing dead-code warnings (TextPlacement.elevation, TabKind, MTextRunKind::Tab).
