Nothing on the load path checked a sketch's size, and every sketch in the
timeline is solved when a design opens. The solver sizes its dense matrices by
the connected component, so a 30 MB file with 200,000 chained points asked the
allocator for terabytes and the process aborted, which no panic guard can
intercept.
Reject an oversized sketch while the design is still raw JSON, so the typed
arrays are never built, and refuse a connected component with more variables
than fits in a bounded matrix: that component now reports a failed solve and
leaves its geometry alone. 10,000 chained points went from 9.6 GB and 25
seconds to a failed solve in well under a second.
