Rearchitect SDF text from a document-wide collector to per-entity production during tessellation, so each entity owns its glyph quads and composite/nested text is covered for free (no re-explosion, no per-frame document walk). - WireModel gains `text_verts`: glyph quads ride on the wire, so they are cached by the tess memo, cloned on hit, and transformed by the block expand loop exactly like `points`. - Text arm (tessellate.rs) builds the quads when SDF is on and suppresses the strokes; render gathers text_verts from the viewport wire set (`gather_text_verts`, cached on wire content id) — the old collector is removed. Covers model, dimension, table, block-internal and paper-sheet text uniformly. - MLEADER text (lays out via layout_mtext, not the Text arm) gets its own SDF branch driven by the per-run GlyphRun. - Pick box comes from the rendered glyph quads (true text extent), not entity_aabb which mis-places the box for MTEXT; composite paths no longer clobber the empty text wire's tight AABB (dim pick box hugs the text). - Selection / hover highlight via a text-highlight overlay (upload_text_ highlight, keyed on selection_generation) mirroring the selected-wire xray overlay; base glyphs stay neutral so a deselect leaves no stale tint. - Debug: env OCS_TEXT_BOX draws each run's glyph-bounds rectangle.
