feat(client): add logPrefix option to SorokitClientConfig #257

[gitGolf]

Overview

This PR adds a logPrefix option to SorokitClientConfig so consumers running multiple client instances (e.g. one per network) can distinguish which client emitted each log line.

Closes #257

Changes

🔏 logPrefix Config Option

• [ADD] logPrefix?: string to SorokitClientConfig in src/client/createSorokitClient.ts

  • Passed as prefix to createLogger when no custom logger is provided.
  • Ignored when a custom logger is supplied.

• [ADD] prefix?: string to LoggerOptions in src/shared/logger.ts

  • Applied as the first argument to console.debug/info/warn/error (default: "[sorokit]").
  • Enables distinct prefixes like [app:testnet] or [sorokit:mainnet].

• [ADD] Tests in src/tests/logger.test.ts

  • createLogger({ prefix: "[sorokit:testnet]" }) emits with the custom prefix.
  • createSorokitClient({ debug: true, logPrefix: "[app:testnet]" }) logs with the custom prefix.
