"Local" stops being a one-way door, and the head search stops skipping

Answering Eric's question — no, a local game never looks itself up again
— by making it possible. A local row's Titles line gains "look it up",
reopening it through the SAME cascade resolve uses (board games,
truncation heads, then RPGGeek) rather than the partial re-implementation
reopen_match had; that cascade is now one shared find_candidates()
instead of two drifting copies. Review's manual (f) re-search falls back
to RPGGeek too.

That exposed a real matcher gap: truncation heads jumped from
"drop the last word" straight to "first two words", so a printed title
that buries the real name in the middle was unreachable — "ALICE IS
MISSING A SILENT ROLE PLAYING GAME" never tried "ALICE IS MISSING".
Heads now shrink from the right, longest first (bounded at six, since
each is a rate-limited request); only exact normalized matches count for
heads, so shorter heads cannot match loosely.

Both of Eric's Alice Is Missing rows now find their RPGGeek entries
(311654, and 380459 for Silent Falls) and await his picks in review.
