Each trace frame now shows the offending source line with a `^` caret under the column — in the catch-handler formatter, the failable-main C reporter, and the comptime path. The source line is embedded at compile time as a 5th Frame field (line_text), not read from disk at runtime: the file field is a basename and a runtime read would add a filesystem dependency that fails under the test harness and on locked-down targets. - errors.lineAt(src, offset): shared helper for the whole source line. - Frame gains line_text (mirrored in emit_llvm getFrameStructType, trace.sx Frame, sx_trace.c SxFrame). emitTraceFrame embeds it; the interp .trace_resolve extracts it from the source map. - trace.sx (new spaces helper) and the C reporter render the line + a col-aligned caret, guarded on a non-empty line_text. Snapshots 243/244/247/253 regenerated. Gates: zig build, zig build test, run_examples.sh -> 291 passed.
