Every source string literal without an established Next root was tested
against /(?:^|\/)app\/(?:[\s\S]*\/)?page(?:\.[cm]?[jt]sx?|-[^/?#]+\.js|)(?:[?#].*)?$/u.
The unanchored search restarted at every app/ segment and rescanned to the
end of the literal, and each page? or page# candidate scanned to the next
line terminator before $ failed. A long literal therefore took quadratic
time on the analysis thread: about 6 s for a 256 KB literal of repeated
app/ segments, and 3.5 s for 224 KB of x/page? followed by a newline.
The first app/ segment admits every later page segment, and . cannot cross
a line terminator, so a query or fragment after the page filename starts on
the last line. Test the tail after the first app/ segment one page segment
at a time instead; results are unchanged.
