Hendrik Liebau dae438dc0d Stop printing a stack frame for error message text (#97829) ...

Next.js printed a stack frame that does not exist for an error whose
message ends with text that looks like a file location. A logged
connection failure read `at <unknown> (Error: connect ECONNREFUSED
::1:45999)` in front of its real frames.

`stacktrace-parser` tries five patterns on every line, and the pattern
for JavaScriptCore makes the `<name>@` prefix optional. That pattern
`:<line>:<column>`, and a line of an error message can end that way. A
JavaScriptCore frame always holds `@`, also at the top level, so the
prefix is not optional in a real stack.

The patch for `stacktrace-parser` now requires that prefix. A line of a
message no longer becomes a frame, and every JavaScriptCore frame still
parses, including one whose path holds a space.

A Turbopack build error puts the file and the position of the error in
its message, and the parser read that line as a frame as well. That
frame is gone now, and the location stays in the message. The snapshots
of the build errors record the change.
