v2.0.0

UniswapSharp 2.0.0 — upstream parity with Uniswap/sdks@35c4e35

Clears four correctness bugs (inverted MixedRouteSDK.MidPrice across
native/wrapped boundaries, undecodable ACROSS_V4_DEPOSIT_V3 encoding, unfloored
V4 exact-out legs, sepolia TickLens pointing at multicall) and adds the
direct-transfer, quick-launch and instant-launch surfaces.

Major because output changes: BuildPositionDefinitions takes the v4 currency
ordering pair and mirrors custom asymmetric LBP ranges onto the reciprocal
band, and ResolveNewPoolTickSpacing supersedes FeeToTickSpacing with different
resolved values.

1920 tests green on Linux/Windows/macOS, zero warnings.
