alii

Implement a new JavaScript native/builtin function (e.g. Array.from, String.prototype.trim, Math.abs).

Run the full test262 execution suite and regenerate the conformance chart.

Verify a change to the AL compiler/VM by driving the real `al` binary end-to-end. Use before committing anything that touches crates/al_core (parser, types, core_ir, bytecode) or crates/al (vm, cli, lsp, repl).
