realign with api changes

base support

Pull request overview

This PR realigns the TypeScript SDK and accompanying examples/tests/docs with updated API behavior, adding bidirectional Solana ↔ Base swap support (including EVM-source swaps returning an ordered transaction array) and updating the swap fee endpoint to return a structured fee breakdown.

Changes:

• Update SDK types to support EVM transaction arrays for Base → Solana swaps and add helper functions to differentiate response shapes.
• Replace the old flat SwapFeeResponse with a SwapFeeBreakdown shape (keeping SwapFeeResponse as a deprecated alias) and update tests/e2e to match.
• Update CLI, package metadata, and READMEs to document/install/support bidirectional swap flows.
