The paint Output write loop had two x-bounds guards Ink lacks, which dropped a whole wide
char -- including its in-bounds leading cell -- when only its trailing cell exceeded the
width, so an edge-aligned "aa你" rendered as "aa". Ink's Output write loop has no bounds
check: it writes both cells and lets the past-width placeholder be dropped as a sparse hole
by line.filter(undefined) + trimEnd. Removes the two guards to match (output.ts:272-308);
box-level overflow:hidden clipping is unchanged (the separate clipH sliceAnsi path).
Un-skips the non-hyperlink-OSC overflow-wrap test, which this also fixes (the now-visible
OSC bytes no longer push the trailing char off a clipped edge) -- verified "abcde\nfghij"
against the Ink reference. Adds a wide-char-at-edge test.
