PumpFun V2 WSOL quote-pool handling in sol-trade-sdk

Recoordinate released sol-trade-sdk v4.0.17 to fix SOL wrapping logic for PumpFun V2 quote-pool buys.

The release addressed a bug in 0xfnzero/sol-trade-sdk where callers using native SOL input with `use_exact_sol_amount = Some(false)` on PumpFun V2 WSOL quote pools would fail [1]. The SDK now auto-wraps SOL for the WSOL quote budget before sending `buy_v2`, ensuring the transaction succeeds. At the same time, the fix preserves explicit WSOL input semantics: callers already holding WSOL and specifying input mint WSOL no longer receive an unwanted extra native SOL wrap unless they explicitly request input ATA setup [1]. Documentation in the README and PumpFun quote-pool guide were updated to reflect the new version.
