Implement float IR operations: 25 words compiled to native WASM f64
Convert 25 float words from host functions to IR primitives:
- Stack: FDROP FDUP FSWAP FOVER FNIP FTUCK
- Arithmetic: F+ F- F* F/ FNEGATE FABS FSQRT FMIN FMAX FLOOR FROUND
- Comparisons: F0= F0< F= F<
- Memory: F@ F!
- Conversions: S>F F>S
24 new IrOp variants compiled to native WASM f64 instructions.
EmitCtx struct threads f64 scratch locals through all emit functions.
Float constant folding: 1.5E0 2.5E0 F+ folds to PushF64(4.0).
Float peephole: PushF64+FDrop, FDup+FDrop, FSwap+FSwap eliminated.
Float literals now compile as PushF64 IR ops instead of anonymous host calls.
~420 lines of Rust closure code removed from outer.rs.
All 14 optimizations now implemented. 430 tests passing.
