Features

• Hold-to-release for missiles and bombs — default hold 0.9 s before vanilla WeaponManager.Fire proceeds.
• OUT OF ARC geometry — extended hold up to 1.3 s (configurable) when solution is marginal.
• Denied states never release — SafetyIsOn, not Ready, SalvoInProgress, remoteSim, etc.
• Gun burst limiter — optional auto-cut after 1.0 s continuous trigger (configurable).
• Multiplayer safe — mod sends no custom Cmd* / Rpc*; launch still occurs only through vanilla Pilot.Fire → WeaponManager.Fire.

Validation checklist (SP/MP)

1. Select missile or bomb station; keep gun excluded if testing missiles only.
2. Hold Fire:
   • valid solution → release only after DefaultHoldSeconds (default 0.9 s);
   • OUT OF ARC → release only after OutOfArcHoldSeconds (default 1.3 s).
3. Denied launch states (SafetyIsOn, not Ready, SalvoInProgress, remoteSim) must never release.
4. Guns: hold trigger continuously → fire stops after GunBurstSeconds; release and press again → next burst starts.
5. Multiplayer: confirm no custom network messages; launch still via vanilla weapon pipeline only.
