`_count_diff_lines` skipped every line starting with "+++ "/"--- " to drop
difflib's two file headers. But a deleted hunk-body line whose content
begins with "-- " (e.g. a SQL comment `-- get users`) becomes the diff
line `--- get users`, and an added `++ ...` line becomes `+++ ...`, so
those were dropped too — undercounting the user-visible +N/-M change
summary (WorkspaceChangeSummary, per-file WorkspaceFileChange, and the
run-event string in recorder.py).

`difflib.unified_diff` always emits the two headers first, so skip them
by position (`lines[2:]`) instead. Hunk `@@` lines start with `@` and are
still ignored. Numeric/plain diffs are unaffected.
