[Domain] add pressure risk summaries, overlays, and feedback

[95x8x9]

Summary

• add pressure hotspot, compression exposure, and critical pressure event metrics across all scenarios
• store pressure summaries in result artifacts and expose pressure overlays and summary cards in the result views
• add live pressure feedback for per-agent compression force, exposure, and movement modifiers
• apply soft local pressure feedback in motion via speed reduction and stronger agent/barrier avoidance
• optimize feedback updates with spatial-index neighbor probes and staggered refresh for quiet agents
• add regression coverage for pressure metrics, result summaries, overlays, floor separation, motion slowdown without freezing, and quiet-agent decay reuse

Area

• Engine
• Domain
• Application
• Docs
• Build
• Analysis
• Chore

Architecture Check

• I kept the dependency direction �pplication -> domain -> engine.
• I did not add Qt UI code to src/domain.
• I did not add domain or �pplication dependencies to src/engine.
• I used src/ as the include root.

Verification

• cmake --preset windows-debug
• cmake --build --preset build-debug
• ctest --preset test-debug
• Not run (reason below)

Risks / Follow-up

• pressure feedback still affects only local movement; route replanning, exit reselection, and urgency changes remain out of scope
• project persistence for pressure result summaries is still a follow-up task
