Soroban Client: Improve Error Handling in JavaScript/TypeScript

[manoahLinks]

Enhance the error handling mechanisms in the Soroban JavaScript/TypeScript client SDK to provide more informative and actionable error messages to developers.

@ayush99336 has applied to work on this issue as part of the Stellar Wave Program's 4th wave.

Greetings! I have experience with Frontend development and SDK design and can enhance the error handling for the Soroban client. I’ve reviewed the need for more informative and actionable messages, and I’m ready to refactor the catch blocks to parse Soroban-specific error codes, XDR decoding failures, and RPC simulation errors into a structured format for developers. I estimate about 4 hours to implement the error mapping and add relevant documentation or examples for the new error types.

I’d like to start work on this as soon as you assign it to me. Thank you, looking forward to working with you!
