An Established (Tier-4) home can draw a second companion. Both pets show up on
the sheet and the town showcase, level via babysitting, and wear their own
barding (!thom pet2buy <tier>).
Combat: both pets contribute their attack/deflect/whiff procs at half weight —
DerivePlayerStats now averages over the active pets, so a pair reads as roughly
one full pet (flavor-forward, not a stat spike; difficulty-neutral). The average
reduces to identity over a single pet (x/1==x, 0.0+x==x, 3+(2L+1)/2==3+L), and
the engines still roll one proc per channel per round, so the single-pet path
and TestCombatCharacterization golden stay byte-identical. Pinned by
TestDerivePlayerStats_OnePetIsByteIdentical + the golden.
Scope kept deliberately flavor-forward: pet 2 carries identity/level/barding and
the three combat procs only. The morning-defense buff, death/ditch-recovery
save, and the level-10 supply-shop unlock stay pet-1 mechanics — no second
defensive multiplier stacks, and the one-pet path is untouched by construction.
Storage: parallel pet2_* columns on player_meta + Pet2* mirror on
AdventureCharacter (absent == no second pet, DEFAULT '' correct for every
pre-existing row, no backfill — the N2-temper / P4-party precedent). Pet-1 code
paths are untouched. Arrival reuses the chase/feed/type/name DM flow, slot-aware,
gated HouseTier>=4 with an established first pet.
Review fixes folded in (high-effort /code-review, 3 angles): pet-2 barding block
no longer hidden when pet-1 is chased away; showcase tie-break restored
(level desc, then name); petGrantXP collapsed onto the shared level-up helper;
dead-param armor-buy wrappers inlined; pet-2 barding tagged with its own euro
ledger reason.

Mechanical `gofmt -w ./internal ./cmd`. Mostly struct-field realignment that
had drifted, plus a few trailing-newline fixes. No behaviour change — gofmt is
semantics-preserving, and build/vet/test are green either side.
Split out from the code-review fixes that follow so those stay reviewable
instead of hiding inside a wall of realignment.
