* Space Lua: Improve numeric types semantics

Add numeric result normalization for arithmetic operations:

* Integer operations preserve int type, collapse -0 to +0
* Float operations preserve float type, maintain -0.0
* Division always produces float results

Fix for-loop variable type tracking:

* Loop variable type determined by start/step parameters
* Integer loops produce integer variables
* Float/mixed loops produce float-tagged variables

Implement table key normalization:

* Integer-valued floats (1.0, 2.0) normalize to integer keys
* All zero variants (0, 0.0, -0.0) map to same key
* Non-integer floats (1.5) remain distinct keys

Add tests for:

* Arithmetic type preservation across operators
* For-loop type modes (int/float/mixed)
* Table key equivalence and normalization
* Edge cases with zero, -0.0, and special values
* Standard library `type` and `math.type`
