Spawner Tweaks: No Damage When Blocked

About the mod:

Starting from Factorio v.2.1 blocked spawners produce acid cloud that damages blocking buildings (e.g. walls, pipes). This mod completely removes the damaging part of the effect with optional twists.

Features:

• Removes the destructive acid damage effect entirely from blocked unit spawners.
• A startup setting lets you choose exactly how blocked spawners behave:

Remove acid cloud:
- Deletes the blocked spawner reaction event entirely, leaving them completely silent.

Acid cloud is a pollution:
- Removes the damaging aspect of the acid cloud and swaps it with pollution creation instead. The spawner itself will vent localized pollution consistently without melting your infrastructure.
- In pollution mode, a zero-damage copy of the original green acid cloud is preserved, providing a clear visual warning that a spawner is choked without hurting nearby structures.

• Includes a startup option to select your preferred biter spawning layout. Keep the tighter Factorio v2.1 vanilla behavior or revert to the classic, sprawling v2.0 layout pattern (3x3 radius and spacing).
