Map expansion API for larger construction area mods

[tajemniktv]

Core-side tracking issue for supporting map/construction-area expansion mods.

Linked mod-side issue: TajsMods/MapExpansion#1.

Player request context:

• Players want a bigger construction area, roughly 2x current size.
• Large schematics often do not fit after paste or portal workflows.
• Manual post-paste adjustment is annoying and fragile.

Core MVP:

• Provide a stable API or hook point for mods to adjust construction/workspace bounds.
• Avoid relying on editor-only changes that do not work in shipped builds.
• Keep vanilla behavior unchanged unless a mod requests expansion.
• Make bounds changes safe for node placement, selection, wiring, camera movement, and save/load.

Implementation notes:

• Prior attempts suggest patching the relevant window/container script directly may be unreliable in the shipped build.
• Core may need to expose a helper/hook around the game script that owns workspace bounds, placement validation, or camera limits.

Acceptance criteria:

• A mod can request larger workspace bounds through Core.
• The request is applied consistently in shipped builds.
• Existing saves and vanilla behavior remain safe when no mod requests expansion.
• Diagnostics/logging make it clear whether expansion was applied or failed.
