fix(auth): respect user-provided auth options in createBrowserClient

[meck93]

Summary

• createBrowserClient hardcodes autoRefreshToken, detectSessionInUrl, and persistSession after spreading options.auth, overwriting any caller-provided values
• Use nullish coalescing (??) so explicit options are respected, falling back to current defaults (isBrowser() / true) when not set
• Adds tests verifying passthrough of all three options

Fixes #108

📝 Walkthrough

Summary by CodeRabbit

• New Features

  • Browser client now supports configuration of authentication options, including automatic token refresh, session detection from URL parameters, and session persistence settings, with sensible defaults.

• Tests

  • Added test coverage for authentication configuration options and default behavior validation.

Walkthrough

The PR addresses a bug where user-provided auth options were being ignored when creating a browser client. The createBrowserClient.ts now uses nullish coalescing to respect user-provided values for autoRefreshToken, detectSessionInUrl, and persistSession while maintaining browser-appropriate defaults when these options are not specified. Corresponding test coverage has been added to verify that these options are properly passed through to the client.
