Implement reactive text nodes & fix LLVM syntax for clang 20

Browse Source

**Reactive Text Nodes:**
- F-strings with signal dependencies now update automatically
- Added js_create_text_with_int() and js_update_text_with_int() for efficient "prefix{int}" pattern
- Text nodes stored in @reactive_text_N_node globals for updates
- Scan and track f-string dependencies during collection phase

**Binary Operations:**
- Implemented BinOp support in parser and codegen
- Maps Add → add i32, Sub → sub i32, Mult → mul i32, Div → sdiv i32, Mod → srem i32
- count = count + 1 now generates correct arithmetic instead of store i32 0

**LLVM Syntax Fixes (clang 20 compatibility):**
- Fixed getelementptr syntax: removed parentheses around type
- Before: getelementptr inbounds ([N x i8], [N x i8]* @str, ...)
- After:  getelementptr inbounds [N x i8], [N x i8]* @str, ...
- Created _emit_string_ptr() helper for consistent string pointer generation
- Fixed in: element creation, attribute setting, event binding, select instructions

**Runtime (ritz-runtime.js):**
- Added js_create_text_with_int(prefix, intValue) - creates text node with "prefix" + intValue
- Added js_update_text_with_int(node, prefix, intValue) - updates text content

**Result:**
✅ TextInput counter increments/decrements correctly
✅ Tabs example works (reactive attributes, conditionals)
✅ Both examples compile with clang 20
