[sync]: program 0.2.2

[dannxbt]

DBC SDK 1.6.0

Syncs the SDK with dynamic bonding curve 0.2.2.

Added

• client.partner.createConfig2. Pass transferFeeParameters for a base-mint transfer fee, or null when there is none. 0 basis points is valid only with TransferFeeWithheldAuthority.Partner and MigratedTransferFeeAuthorityOption.Immutable.
• TransferFeeWithheldAuthority and MigratedTransferFeeAuthorityOption.
• Swap quotes account for Token-2022 transfer fees and return includedTransferFeeAmountIn and excludedTransferFeeAmountOut. getSwapQuoteTransferFees fetches the quote mint and the current epoch.
• getQuoteFromInputAmount and getQuoteFromOutputAmount quote a buildCurve result (ConfigParameters) before a pool exists. client.pool.swapQuote2 quotes an existing pool and requires currentPoint.

Changed

• createConfigAndPool and createConfigAndPoolWithFirstBuy always use createConfig2. Omitting transferFeeParameters is the same as null.
• A base transfer fee, or a quote mint with a non-zero transfer fee or a live transfer fee config authority, requires a constant token supply, no locked vesting, MigrationFeeOption.Customizable, and MigratedCollectFeeMode.Compounding. The base fee is Token-2022 only and at most 10%.
• MigratedCollectFeeMode.Compounding allows compoundingFeeBps of 0.
• Curve builders size the migration deposit from ceil(migrationQuoteThreshold * (100 - migrationFee.feePercentage) / 100), then convert that quote amount into the migration base. buildCurveWithLiquidityWeights and buildCurveWithCustomSqrtPrices use constant product for Compounding, and concentrated liquidity for QuoteToken and OutputToken.
• buildCurveWithTwoSegments and buildCurveWithMidPrice keep a fractional percentageSupplyOnMigration when sizing the migration base.
• Liquidity vesting frequency is floor(totalDuration / numberOfPeriods).
• Exponential fee schedulers, including the migrated market-cap scheduler, choose reductionFactor with the program's Q64 decay so the last period stays at or above the requested ending fee.
• Rate-limiter validation checks the fee at u64::MAX.
• Swap quotes reject amounts outside the program's u64 and u128 bounds. Insufficient-liquidity quotes use the program error text, Liquidity in bonding curve is insufficient.
• Synced the DAMM v2 IDL and cp_amm.so fixture to cp_amm 0.2.5.
• calculateFeeSchedulerEndingBaseFeeBps uses the program's integer conversion, numerator * 10_000 / FEE_DENOMINATOR.

Deprecated

• client.partner.createConfig in favour of createConfig2. createConfig and createConfigWithTransferHook reject a quote mint with a non-zero transfer fee or a live transfer fee config authority.

Breaking

• Swap quotes for a Token-2022 quote mint require quoteMint and currentEpoch.
• SwapQuoteConfig is removed. getQuoteFrom* takes ConfigParameters and does not accept a decoded PoolConfig.
• getMigratedPoolFeeParams throws for MigrationFeeOption.Customizable when migratedPoolFee.poolFeeBps is not set.
• swap, swap2, claimPartnerTradingFee, and claimCreatorTradingFee reject transfer-hook pools. Use swap2WithTransferHook, claimPartnerTradingFee2, and claimCreatorTradingFee2. Standard pool creation rejects a transfer-hook config, and transfer-hook pool creation rejects a standard config.
