Custom Mobs Framework

# Changes in Build 076a

- **Melee Animation Stalling Fix**:
  - Corrected the melee attack goal to keep the attacking behavior active when close to targets (`followingTargetEvenIfNotSeen = true`).
  - Resolved the bug where the attack animations would glitch/cancel and stop looping when mobs were sticking directly to the player.
- **Configurable Melee Damage Delay**:
  - Added a "Melee Damage Delay" field and tooltip under the `MELEE` goal in the Creator GUI.
  - Implemented a delayed attack timer on the server that checks if the target is still within the mob's range before executing the damage calculation.
  - Added support for custom sound events when triggering melee attacks.
- **Sticky Projectiles**:
  - Added a "Sticky projectile" checkbox to the projectile creator Basics tab.
  - Sticky projectiles now physically pin themselves onto targets they collide with, following their movement smoothly.
- **Real Bounding Box Projectile Collision**:
  - Re-engineered projectile collision checks to respect the projectile's custom hitbox dimensions, preventing large projectiles from cleanly passing through entities.
- **Extended Ground Summon Attack**:
  - Added configurable "Upward Speed" and "Max Height" fields to the `SUMMON_GROUND_ATTACK` goal in the Creator GUI.
  - Projectiles now rise at the defined velocity and start falling naturally after reaching the specified height limit.
- **Localization updates**: Updated all 9 translation files to include the new tooltip descriptions and checkbox labels.
