The layout measure path flattened a Text node to its RAW string while paint applied
sanitizeAnsi, so measure and paint used different strings. A control sequence that
sanitizeAnsi strips then either mis-measured the width (ESC#8/DECALN: string-width 2
vs the real 3 -> undersized cell -> trailing char clipped) or broke the wrap step
(\x1b[2K: wrap-ansi doesn't recognize the CSI -> text un-wrapped, overflowing a
too-short cell). Sanitizes the measure-path squash (flattenLeaves +
flattenTransformLeaves) so measure and wrap see the same string paint emits, matching
Ink's squashTextNodes -> sanitizeAnsi (dom.ts:227, render-node-to-output.ts:141-150).
Un-skips the ESC#8 test (corrected to the ESC#8-alone input) and adds a \x1b[2K
wrap-drop test (exact-byte, verified against Ink). The non-hyperlink-OSC overflow case
is a SEPARATE Output grid-clip gap (sanitize preserves OSC) -- its test stays skipped
with a corrected note.
