feat(rate): add Morris evaluator adapter

[d-sorgcodexagent]

Summary

• bind shared Morris execution to genuine fixed-ball double-pendulum Rate simulations
• support only ten globally modeled, registry-unit-checked factors and reject the fixed-ball no-op impact_time_offset_s
• export the exact 17-output Rate Morris catalog with strict hit/miss/failure availability
• extract one shared simulation capture/projection seam and one DRY global-config application seam
• update SPEC 1.16.27 and all three canonical Rate handoffs

Verification

• 23 focused adapter/request tests
• 75 Rate variation tests
• 136 shared variation tests
• Ruff check and format
• hosted-style MyPy on five production files
• changed-policy, file-size, AST, diff, import-smoke, and secrets gates
• independent exact-commit review: GO, no actionable findings

Scope boundary

The adapter uses the existing sampled-point/spherical-ball contact model; it does not claim clubhead-mesh, swept-collision, compression, or a proven genuine double-pendulum fixed-hit fixture. PyQt/React presentation, export, detailed per-sample failure diagnostics, and UpstreamDrift consumption remain follow-up scope.
