Add per-method request timeout configuration

[Kingsman-99]

Overview

All SDK calls share a single global timeout. Read-heavy methods like getLeaderboard may need longer timeouts than quick lookups like getInvoice. Add per-method timeout overrides.

Acceptance Criteria

• StellarSplitSDK({ timeout: { default: 10000, getLeaderboard: 30000, getInvoiceHistory: 20000 } }) config
• default timeout applies to any method not explicitly listed; defaults to 10 000 ms
• Per-call override: sdk.getLeaderboard({ timeout: 60000 }) for one-off extension
• Timeout implemented via AbortController — request aborted (not just ignored) on timeout
• Throws RequestTimeoutError with { method, timeoutMs } when timed out
• Retry logic respects per-attempt timeout — each retry gets a fresh timeout window
• sdk.getTimeoutConfig() returns the resolved timeout for each known method
• Unit tests: fast method times out correctly; slow method with long timeout succeeds

Hi,
Please assign me this task. I’ll implement per-method and per-call request timeout configuration with AbortController-based cancellation, retry-aware timeout handling, timeout configuration accessors, and unit tests.

Hi! I'd like to work on this issue.

I'll implement configurable per-method request timeouts while preserving a sensible default for all SDK calls. The solution will support one-off per-call overrides, use AbortController to cancel timed-out requests, expose the resolved timeout configuration via getTimeoutConfig(), and ensure retries receive a fresh timeout window. I'll also add comprehensive unit tests covering default behavior, method-specific overrides, per-call overrides, timeout errors, and retry handling.
