Brandon Schneider e0935f01e0 feat(lean): port receipt-density scoring to Semantics.RRC.ReceiptDensity
Adds Semantics/RRC/ReceiptDensity.lean — a new Lean module that ports
the entire scoring pipeline from pist_receipt_density_injector.py into
Lean-native Q16_16 fixed-point arithmetic:

  spectralQuality   ← spectral_quality()   (0.24/0.18/0.18/0.12/0.12/0.16 weights)
  shapeAgreement    ← shape_agreement()    (exact=1.0, proxy=0.82, any=0.35)
  axisScore         ← axis_score()         (hits/4, capped at 1.0)
  statusScore       ← status_score()       (BLOCKED=0, HOLD=0.12 … VERIFIED=0.84)
  computeDensity    ← compute_density()    (density: 26/24/26/24, confidence: 20/20/28/32)

No Float in compute paths — all arithmetic is Q16_16 (raw Int, scale=65536).
Two #eval witnesses verify CANDIDATE/VERIFIED case outputs.

Build: lake build Compiler → 3311 jobs, 0 errors (baseline preserved).

Update shim BOUNDARY comments:
  pist_receipt_density_injector.py → Semantics.RRC.ReceiptDensity
  rrc_pist_shape_alignment.py      → Semantics.RRC.Emit
