Subject: Melee killbot: 360-degree crowbar silent aim

- New feature (default on): while the local player's active weapon is the
  crowbar, pick the nearest visible hostile NPC within the 75-unit crowbar
  range, sorted by distance to its collision AABB, and attack it through the
  normal silent-aim path (usercmd view + IN_ATTACK, movement preserved,
  rendered view restored at FRAME_RENDER_START).
- Prefer the nearest visible hitbox center; fall back to the AABB center /
  closest point when bones are unavailable. Reuses the existing friendly /
  neutral and life-state filters and the world-only vischeck.
- Detect the active weapon from the client m_hActiveWeapon handle, with the
  authoritative server m_hActiveWeapon handle as a fallback (client entity
  index from the low 16 bits).
- While the crowbar is active and this feature is on, skip the gun aimbot,
  triggerbot and silent aim so they do not fight over the usercmd view.
- Menu: Melee killbot -> Active; config [melee] active=...
