The desktop UI needs to create events, trade on both sides of an order
book, and show who is participating in an event, none of which the api
module could express so far.
Add AccountContext for looking up ledger accounts by owner, and give
CatalogContext an openEvent operation plus createEvent, taking either a
CreateEventRequest or its fields spelled out. createEvent defaults to
a "Not implemented" error so existing implementations keep compiling
until they support it.
Let GuessMarketContext.placeOrder take an explicit side, keeping the
old signature as a default method that places a BUY so current callers
are unaffected.
Add OrderBookDTO and BookOrderDTO to describe per-option books with
best bid, best ask and spread, and ParticipantDTO for a user's
position, fees and P&L in an event. Carry the order books and
participants on EventDetailDTO and the market maker's name on
EventSummaryDTO.

Move AccountDTO/MarketDTO/MarketStateDTO/PurchaseReceiptDTO/TradeRowDTO
out of the catch-all api package into model.market (and LedgerDTO into
model.ledger), matching the existing model.event convention so DTOs
live next to the domain they describe rather than in the interface
package. Relocate LedgerMapper from mapper.v2 to infrastructure.adapter
to match the module's established package layout, and update all call
sites and imports accordingly.
Also register the ui-desktop module in the build tooling: add it to
MODULES, add openjfx to the shipped runtime libs, and generalize
package.sh so each executable module (ui-console, ui-desktop) gets its
own Main-Class/Class-Path manifest and run script instead of
special-casing ui-console. Fold long Class-Path manifest lines at 72
bytes per the JAR spec, since adding ui-desktop's dependencies pushed
the line past the limit.

Groups them with the other event-domain enums instead of the general
api package, and updates all call sites accordingly.

state I/O
Adds a full pre-load validation pass for GM XML seeds (ids, names,
options, commission, LMSR liquidity), replaces IO.print with
System.out, and surfaces detailed error messages across load/save
commands instead of generic failures.

- Event ledger now grows on purchase and shrinks on payout, mirroring
the exact amounts moved on the buyer's ledger (it previously had a
Ledger object that nothing ever wrote to).
- Settlement and event-detail views now show the winning market's
display name instead of its raw key; event details are viewable for
settled events too (the picker previously excluded anything not
ACTIVE).
- LMSR events seed their ledger with a SUBSIDY entry for the market
maker's worst-case loss (b * ln(outcomes)), reusing the existing
cost() function rather than recomputing the formula.

Move XML loading infrastructure and models under service/catalog, and
split order execution into a real pipeline: RiskEngine checks the order,
MatchingEngine matches it, FulfillmentContext books the resulting trades,
and SettlementContext resolves winning markets. GuessMarketContext.buyShares
becomes placeOrder(price, quantity), and TradingMechanism.buy now returns
matched trades directly instead of a single TradeExecution.

Moves Event/Ledger DTOs out of the flat api package into
api/model/{event,ledger}, and moves LocalCatalogContext and order
matching logic into dedicated service/catalog and service/matching
packages, replacing TradingOperation/TradingOperationImpl.

Split GuessMarketContext into a separate CatalogContext for read-only
event listing, wrap fallible operations in Result<T> instead of throwing,
and wire load/save of events and users through a JSON Wrapper.

Implement LocalGuessMarketContext.buyShares/loadEvents via a new
TradingOperation and Loader, backed by in-memory repositories. Replace
the ConsoleInputProviderFactory/ConsoleOutputProviderFactory pattern
with picocontainer-injected providers, and drive the menu from a list
of MenuCommand implementations instead of a hardcoded printout.

GuessMarketContext gained a richer surface (loadEvents/listEvents/
buyShares/closeEvent/account/save-restoreState) backed by new
EventDetailDTO, MarketStateDTO, OptionStateDTO and PurchaseReceiptDTO.
The old engine-module provider implemented the previous shape and is
removed; market.guess.service.LocalGuessMarketContext replaces it as a
stub, each method throwing UnsupportedOperationException pending a
real implementation.

Introduce MechanismType and rename CommissionChargeType to
CommissionTiming to better describe LMSR vs order-book events.
LocalGuessMarketContext.GetAllEventsAsync is stubbed pending the new
mapping.

InputProvider/OutputProvider were api-layer types only ever implemented
by the console UI; relocate them there. Drop the unused
GuessMarketEngine/LocalGuessMarketService pair, flesh out LoadResultDTO
with success/failure variants, and make LocalGuessMarketContext.LoadAsync
report real outcomes instead of an empty placeholder.

PicoContainer wiring
Relocates GuessMarketEngine/GuessMarketContext into market.guess.api so
engine and ui-console depend on a shared contract instead of engine
internals, and makes context loading async (CompletableFuture). Adds
InputProvider/OutputProvider interfaces with console implementations,
wires the console app's Menu through a PicoContainer, and adds the
generated model classes plus vendored picocontainer jar needed to build it.

Move api, engine, ui-console and ui-desktop out of modules/ up to the
repo root and drop the empty exception project (GuessMarketException now
lives in api).
Vendor gson, jaxb, okhttp, openjfx and tomcat under lib/, and group the
JUnit standalone jar into lib/junit/ alongside them.
Rewrite every .classpath: drop the copy-pasted optional="true" that was
masking real build path errors, point the library entries at ../lib/,
and put the JUnit jar on the test source folders so the placeholder
AppTest classes compile.
ui-desktop: take the JavaFX jars off the modulepath (there is no
module-info.java, so module="true" left the packages unresolvable) and
add a Launcher that calls Application.launch, avoiding the "JavaFX
runtime components are missing" check without VM arguments.
engine: add LocalGuessMarketService and the GuessMarketContext provider
interface, and give GuessMarketException the no-arg and cause
constructors they need.
