Jason 2763b4be91 Fix CFAR blocking assignment (= to <=) in clocked block, add Build 15 analysis report ...

CFAR magnitude computation in radar_system_top.v used blocking assignment (=)
inside posedge-clocked always block, creating sim/synth mismatch risk. Changed
to non-blocking (<=). Threshold check now reads previous cycle's magnitude,
which is correct sequential behavior. Regression: 15/15 quick + system TB pass.

Build 15 analysis written to 10_docs/reports/ (not tracked — gitignored).
