phase 4 review fix: strip stale (pending) from GLOSSARY

Phase 4 shipped 40 files including FVG, OB, breaker, mitigation, and
rejection-block concepts — many of which are referenced from GLOSSARY.
Stripped the (pending) marker from every GLOSSARY entry whose target
file now exists. 16 (pending) markers remain, all correctly pointing
to Phase 5-7 deferred files.
