fix(m3): AI-assist scope + confidence gate + grouped wood categories
- inference: _taxonomy_lists hands the model the synced species leaves + wood
leaves + case-insensitive attribute terms (was furniture roots / empty)
- inference: CALL1_SEED pins exact flat schema + *_confidence keys, drops grade
- inference: _gate maps field->confidence key correctly (was species_id_confidence),
reads nested shape as safety net, omits grade (METADATA-40)
- review.svelte: figure gets AI assist, grade dropped from AI (owner judgment)
- MultiSelect: grouped mode (parents non-selectable headers, selectable leaves)
- METADATA-40 updated: grade not suggested by Call 1
