ajandClaude Opus 5.5 479883e7ac feat(cutting): tab parts by width when the plate has no support bed
With support tabs on and no support bed, nothing was tabbed and nothing
said so. A new no-bed width range (NoBedTabMinWidth..NoBedTabMaxWidth,
the short side of the part's minimum-area bounding rectangle) now picks
the parts to tab instead. SupportTabSettings.Analyze makes the choice
for Plan Cutting, hand-placed lead-ins and the pre-post review; without
a bed any tab clear of inside corners counts. With no bed and no range,
the plan notes that nothing was tabbed. Cutting Settings > Tabs gains
the range fields, and the values persist with the cutting parameters.
