Siegfried Pammer 04505bbdf2 Highlight and scroll to the changed instruction in the ILAst view The C# debug-steps view highlights and centers the exact AST node a transform changed; the ILAst view already had the step tree and replay-at-step but produced no highlight. Bring it to parity. IL rendering has no token-writer seam like the C# output visitor, so per-instruction text spans are recorded by bracketing ILInstruction.WriteTo via a new INodeTrackingOutput. The dominant inst.ReplaceWith(newInst) transform pattern detaches the instruction passed to Step, so ILTransformContext gains EndStep to record the produced instruction; Stepper additionally records the position's ancestor chain as fallback candidates before the step-limit throw, so the "show state before" view -- which halts at the selected step -- still resolves to a surviving ancestor (ultimately the ILFunction). The highlight-range resolver is shared with the C# language. Assisted-by: Claude:claude-opus-4-8:Claude Code		6 days ago
