Extracts a single `formatMatchPath` helper used by both the
fast-glob/native code paths and the streaming onMatch callback so
relative paths, trailing-slash handling, and directory markers are
produced consistently. Also drops the retry-without-gitignore fallback
when the gitignored pass returns zero matches, so a broad hidden-file
pattern that is fully ignored stays fully ignored instead of silently
flipping gitignore off on the second attempt.
When a bash tool call requests a timeout outside the allowed 1-3600s
range, the effective clamped value and the originally requested value
are now emitted as a notice appended to the tool output and exposed on
BashToolDetails via requestedTimeoutSeconds. The renderer shows the
clamped+requested pair inline in the timeout badge.
