Author simulation design/results report artifacts from code-grounded network-layer and simulation analysis

[Copilot]

This change delivers the requested technical-report artifacts for the LoRa V2V network layer simulation effort: a code-grounded working memory of the network layer, a simulation-framework summary, and a structured “Simulation Design and Results” report section. The content is derived directly from the repository’s network-layer and simulation/runtime/test sources and organized for deterministic, evidence-based reporting.

• Network-layer working memory (_memory_network_layer.md)

  • Added a structured summary of:
    • frame/header structure and message identity
    • abstraction boundaries (ILinkLayer, ILocationProvider)
    • forwarding evaluation pipeline and suppression mechanisms
    • holdback-delay logic and tunables
    • threading/queue/synchronization model
    • compile-time and runtime configuration surface

• Simulation-framework working memory extension (_memory_network_layer.md → ## Simulation Framework)

  • Appended simulation architecture coverage:
    • scenario runtime composition and deterministic stepping model
    • node embedding of real NetworkManager instances
    • channel/event/timing/impairment models
    • waypoint/mobility handling
    • test harness and metrics collection
    • phase 3/4/5 validation intent by test theme

• Report plan artifact (_plan_simulation_section.md)

  • Added a hierarchical outline for a full “Simulation Design and Results” section.
  • Each section includes explicit source evidence targets (files/functions/structs) to anchor claims in code.

• Final report section (report_simulation_section.md)

  • Added complete sectioned prose matching the planned structure:
    • simulation objectives/scope
    • deterministic runtime architecture
    • channel and mobility modeling
    • validation methodology
    • results grouped by behavioral theme
    • interpretation/limitations
    • confidence summary
