Phase 133 Part 3: Final lcode.cpp Functions (10 more functions)

**Part C Final: Helper & Utility Functions** (10 functions)
- hasjumps: expr (inline helper)
- tonumeral: expr, value (constant folding)
- const2val: expr (constant extraction)
- const2exp: value, expr (constant conversion)
- isKstr: expr (string constant check)
- isKint: expr (integer constant check)
- isCint: expr (C register range check)
- isSCint: expr (sC register range check)
- isSCnumber: expr, intResult, isFloat (numeric constant check)
- exp2const: expr, value (expression to constant)

**Total lcode.cpp Progress**:
- Part A: 6 functions ✅
- Part B: 14 functions ✅
- Part C: 26 functions ✅
- **lcode.cpp COMPLETE: 46 functions modernized!**

**Impact**: All compiler code generation functions now use modern names
- e → expr (300+ occurrences)
- v → value/intValue/intResult (clear semantics)
- Helper functions (hasjumps, tonumeral, is*) all modernized

**Files**: src/compiler/lcode.cpp (46 functions, ~350+ variable occurrences)
**Testing**: All tests pass ✅ (2.07s, slight performance improvement!)
**Risk**: LOW (compiler-only, comprehensive testing)

**Next**: Phase 133 Part D (parser.cpp - 4 remaining functions)
