Two wrap artifacts in the Edit result card, both in wrapEditRendererLine:
- A row that broke inside an intra-line diff highlight ended with inverse
video still active (only the foreground was reset), so the frame's
right-edge padding painted as a default-foreground block. Every wrapped
diff row now closes inverse alongside the foreground reset; the next row
re-opens its own state, so highlights spanning the break render the same.
- The gutter matcher required a marker at column 0 immediately followed by
digits, a shape only produced when marker and number exactly fill the
gutter. Left-padded gutters (" -42│", any line number narrower than the
widest in the diff) and dedup-blanked gutters (" +│" on the added row
of a single-line replacement) fell back to generic wrapping, so their
continuation rows escaped into the line-number column. │-separated gutters
now accept padded and blank line numbers; ASCII "|" gutters still require
the canonical marker+number shape emitted by the plain fallback, so body
lines that merely start with "|", " |", or "123|" keep wrapping
generically.
Regression tests cover continuation-gutter containment, net-inverse-off at
every row end (with a precondition proving a highlight actually crossed a
break), phantom-gutter rejection for pipe- and digit-leading body lines, and
the plain-fallback canonical-row path.
