- Remove global-toolbar (footer with code display) entirely
- Move Generate, Save, Load, New, Tests buttons to algorithm pane toolbar
- Replace prog.generateCode() with prog.generateAndDownload() — creates
a Blob from the IR and triggers a program.ll download via a temp <a>
- Remove copyCode function from helpers.js (no longer needed)
- Remove global-toolbar and .code-output CSS rules
- Add .action-btn styling for the text buttons in pane-toolbar
- Replace all C code generation with LLVM IR (flat DFA model with
bb_ prefix labels to avoid SSA value name collisions)
- Remove c.min.js, add llvm.min.js highlight.js language definition
- Update shell.nix: gcc -> clang, remove sdl3/mesa deps
- Download LLVM Language Reference to docs/llvm/LangRef.html
- Rename #c-code to #ir-code in HTML, JS, and CSS
- Replace _generateIncludes with _generateLLVMDecls for extern
function declarations using LLVM_DECL_MAP
- Add string pool (CodeGen.allocString, stringGlobal, llvmStringArg)
for LLVM IR global string constants with getelementptr references
- Default colour now checks dataset.exitError instead of tagName === 'WC-END',
so success (exit 0) END blocks default to blue, error END blocks to red
- _selectByCode now also sets the HTML value attribute via setAttribute(),
ensuring cloneNode(true) preserves the formatted display value
- Add 4 regression tests for colour defaults, attribute sync, and clone value
