tsconfig compiled docs/ (vendored ccxt samples) and @types/react was missing,
so 269 tsc errors buried the real ones. Scoping the project and adding the
missing type packages left 42 genuine errors in src/, which exposed two bugs:
- lighter: assertSpotBalance's buy branch and createOrder's spot-sell guard
compared the {available, wallet} object against a number, so both guards
were dead. Introduce SpotAssetBalance with a precomputed 'effective' field
(Extract Class) and route all three call sites through it.
- offset-maker: the below-min-sell branch logged 'skip sell' but pushed the
SELL order anyway, and pushed a possibly-null price. Both branches now
match their working sibling.
Also: widen LighterOrder's is_ask/reduce_only to BooleanFlag (the wire format
flags.ts already parses), extract sellableBase (Extract Function, 3 copies),
delete two scripts importing a module that does not exist, add a typecheck
script. tsc --noEmit: 269 -> 0 errors; 218 tests still pass.
