UX S4: magic-item polish — slot fixes, swap-back, shop & sheet truth-up

B4: Slot classifier no longer treats "Springing" / "Snaring" / "Devouring"
as ring matches; tokenises by word boundary instead of raw substring.
Adds DnDSlotCloak so cloaks/capes/mantles/wings stop evicting body armor
from the chest slot. Regenerated magic_items_srd_data.go: boots_of_*,
gloves_of_missile_snaring, bag_of_devouring, talismans, and 6 cloaks all
land in the right slot.

R4: equipMagicItem swap-back returns the prior occupant at full Value
instead of half — swapping a curio shouldn't tax it.

R5: Attunement count is recomputed *after* the swap-back so freeing the
prior occupant's bond opens the slot for the incoming item.

R1: Inventory tags magic_item rows with 🔮 + rarity label and prints a
single equip-magic footer when any are present.

R6: Sheet's Magic Items block marks unbonded items as **(inactive)**
with the reason (cap full vs unbonded), so over-cap items aren't silent.

R7: New activeMagicItemsLine surfaces a one-shot "your curios stir: …"
at combat-start in both the dungeon path and !fight, mirroring the way
class passives are surfaced.

R8/R9: dropMagicItemLoot pretty-prints rarity, drops "wondrous", calls
attunement "needs bonding", appends "auto-uses in combat" for
potions/scrolls, and routes persistence errors to slog instead of
leaking %v into chat.

R2/R3: Curios shelf now shows "Very Rare" not "very_rare", drops the
bare "wondrous" word (the effect line carries it), renders the codified
magicItemEffectSummary above the SRD desc, and ends with a one-line
plain-language "what is bonding" footnote.

R10: Curios stock day flips at 06:00 UTC instead of midnight so EU
players don't see a fresh shelf at 1 a.m. mid-session.

R11: Curios buy resolver disambiguates fuzzy matches — typing "ring"
when several rings are on the shelf lists candidates instead of
silently selling the first.

P1: Greeting grid pairs Curios with an Exit chip so the 2-column
emoji layout doesn't dangle.

P2: Equip-magic empty state trimmed to one line.

P4 (back-from-curios reprompt) deferred — the existing back-flow is
correct, just verbose; not worth the surface-area expansion this
session.

Tests: word-boundary classifier, cloak/chest coexistence, full-value
swap-back. go test ./... + go vet clean.
