fix(brain): enforce r_f=6mm minimum, reject pockets that can't fit fillets
...
- Default r_f raised from 1.5mm to 6mm (machining constraint)
- Default min_pocket_radius raised to 6mm
- Pockets that can't fit r_f at any corner (within 80% tolerance) are
skipped entirely — left solid for more stiffness in tight areas
- Result: 26 pockets (was 432), 187 NX entities (was 13,061)
- Min fillet radius: 4.88mm, all >= 4.8mm (80% of 6mm)
- Mass: 4,601g (was 3,480g — more solid = heavier but manufacturable)

refactor(brain): structured pocket output — 3 lines + 3 arcs per pocket
...
Replaced Shapely buffer-based fillet (59-pt polylines) with exact geometric
fillet computation. Each pocket now outputs:
- 3 straight edges (line start/end pairs)
- 3 fillet arcs (center, radius, tangent points, angles)
NX import updated to use SketchLineBuilder + SketchArcBuilder (3-point).
Total NX entities: ~2,600 (was ~13,000). Includes arc fallback to 2-line
segments if SketchArcBuilder fails.
Also outputs circular hole definitions for future NX circle creation.
