Pull request overview

This PR adds support for passing a custom logger into the React and Vue SDK providers, and ensures the custom logger takes precedence over debug mode (which otherwise uses console).

Changes:

• Add a logger prop to React/Vue providers and thread it into client initialization with precedence over debug.
• Update internal useReflagClient helpers to accept { debug, logger } in the init options object and apply the precedence rule.
• Add/adjust tests and README docs to cover/describe the new behavior.
