Military Arms Core 0.2.0

Shared systems

• Added reusable aircraft, gunship, drone, adhesive beacon and thrown marker model assets and rendering helpers.
• Added shared flight trails, deployment particles and model fade rendering.
• Added 27 reusable firing, engine, impact, fire deployment and handling sounds, bringing the library to 38 shared sound events.
• Added reusable ray targeting and solid-surface projection APIs.
• Added temporary chunk leases with per-mod limits, readiness checks, expiry and independent cleanup.
• Added generic flying A* navigation, swept-body collision checks and shared search budgets, with application-supplied movement and chunk callbacks.

Entity ignition

• Fixed repeated ignition and extinguishing in rain. Additional ignition now respects rain, water, bubble columns, powder snow, Fire Resistance and immunity to ongoing fire damage.
• Kept direct flame and burning-area damage independent of additional ignition.
