prosolis c9128fb0d6 Combat engine §1 (the other half): a cleric can heal a friend at camp
`--target @user` has been advertised by !help and swallowed by the parser since
SP2 — "reserved for SP3, accept and ignore". §1 wired ally heals inside a fight;
out of combat the cleric still could not put a hit point on anybody but himself,
which is most of where a party is actually hurt: between the rooms, not in them.

The target set is the expedition, not the world. In a fight splitCastTarget
resolves against the people in the fight; the standing-around equivalent is the
people you are travelling with, so both `!cast` paths answer the same question.

Only a heal may name somebody else. UTILITY resolves on the caster and everything
else queues as a PendingCast for the *caster's* next fight, where an ally target
has nothing to mean — so a target on those is refused outright rather than
silently dropped, which is exactly what the old parse did.

The ally's row is mutated with one guarded UPDATE inside a transaction, not a
read-modify-write under a second lock (gifting sets the precedent). Two clerics
healing each other at the same instant would otherwise take their advUserLocks in
opposite orders and deadlock the pair of them. The max-HP clamp lives in the SQL
for the same reason.

Refunds the slot on every path that heals nobody — full-HP ally, downed ally, no
sheet, stranger. A slot spent for zero HP is the kind of thing players do not
forgive. All four are pinned end-to-end through the real handler.

A heal is still not a resurrection: it will not raise the dead, same rule the
combat path holds.
