prosolis 01c2cb2f0b Combat engine §1: the hired companion can cast ...

Every spell lookup in the engine is keyed on a Matrix user id and answered
by a dnd_* table. The companion has rows in none of them, deliberately — a
sheet on disk is what would turn him into a real character everywhere. So
the auto-picker's first statement, LoadDnDCharacter(uid), came back nil and
returned "attack", every turn, for the whole fight.

A hired Cleric swung a mace while the party died. Role-fill hands a lone
martial a Cleric, so that was the common case of the feature.

Adds a seat-scoped spellbook: seatKnownSpells / seatSpellSlots /
seatKnowsSpell / consumeSeatSlot / refundSeatSlot. A human seat delegates to
the DB functions verbatim — same queries, same order — so solo combat and the
balance corpus are untouched (both goldens byte-identical). A companion seat
is answered from his synthetic sheet and a slot ledger on his seat's
persisted statuses. The seat is the correct home and not merely the available
one: every expedition hires the same @pete, so a store keyed on his user id
would have two parties sharing one pool of slots.

He gets the same default kit a real character of his class and level gets.
The below-median stays where it was — the level penalty, the never-Masterwork
gear, the absent subclass and magic items. A bespoke weaker spell list would
be a second nerf hidden in a different file.

castActionForSeat was also a live hazard: it loaded the caster through
ensureCharForDnDCmd, whose auto-migration branch, handed a user with no sheet,
builds one at level 1 and *saves* it. Pointed at the companion that silently
makes him a player. He now takes a branch that never reaches it, and a test
counts rows in dnd_character / dnd_known_spells / dnd_spell_slots /
player_meta to keep it that way.

Measured, 640 runs/arm (10 classes x L10,L12 x 4 zones):

  solo                      66.1%
  + Pete, mace-only (HEAD)  83.4%  (+17.3pp)
  + Pete, casting            95.9%  (+29.8pp)

The fix does what it should. It also lands on top of an unpaid §2(a): the
mace-only arm shows Pete was ALREADY a carry, taking the trailing band from
6.8% to 63.6% without casting a thing. The tell is the cleric leader, who
role-fills a *Fighter* Pete — a seat this commit cannot touch — and still goes
26.6% -> 98.4%. That is enemy scaling undercharging for a seat, not spells.
§2(a) is next, and is not optional.
