feat: Astralane QUIC, code review fixes, README & example updates

- Add Astralane QUIC client (astralane_quic.rs) and SwqosTransport::Quic
- README: Astralane QUIC usage, remove third-party doc links, add QUIC to examples
- Code review: API key not in logs, PumpSwap no clone, PDA Result, SELL_DISCRIMINATOR, ensure_wsol_ata refactor, tracing in astralane, only supports fix
- instruction/utils: pumpfun/pumpswap PDA & discriminator unit tests
- trading_client example: SwqosTransport, Astralane QUIC in config
- cli_trading: fix all unused variable warnings (_prefix)
- Add docs/CODE_REVIEW_REPORT.md
