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.
