100 deep row continuation chain

// A `| row hN` continuation chain inside a `-> T` tor impl emits on the
// return-switch fast path: each level nests a `return switch` inside the
// previous arm, growing the indent string by 8 per level. That path
// carried a fixed [128]u8 indent buffer; ~14 nested levels overran it
// (index 132 > len 128 — hit by a synthesized component seed). Growable
// emitters now allocate the run; this impl (20 nested continuations)
// crosses the old cliff and must compile and run.
