Truncating writers (`>`, Unity -logFile) rewrite below any offset, so an offset
turned a stale success into a silent hang. The option, the scan branch, its docs
and its fixtures are gone; the header states the fresh-log-path rule.

F1: log form searches only bytes after WAIT_FROM, so a stale done line in a
reused log is ignored (also makes the per-check cost independent of log size).
F2: pid form prints GONE (no completion evidence). F4: invalid ERE is exit 3.
Mode 100755 recorded for wait-on.sh; other tools/ scripts are still 100644.
F5, F6, F7 recorded as known limitations in the header. Fixtures added.

Same contract as ygg-verify.sh wait (270 s cap, bounded tail, RUNNING exit 99,
exit 98 for a thing gone with no completion evidence). Windows PIDs are found
through tasklist, since kill -0 only knows Git Bash's own. Fixtures in
tools/test-tools.sh; INDEX row added.
