Apply suggestion to clarify parallel tool calling behavior in FAQ

[xingyaoww]

Summary

This PR applies @enyst's suggestion from PR #149 to improve the clarity of the parallel tool calling explanation in the SDK FAQ.

Changes Made

Modified sdk/faq.mdx line 11 to clarify when parallel actions are executed:

• Before: "This allows agents to execute multiple independent actions simultaneously, improving efficiency."
• After: "This allows agents to execute multiple independent actions before the next LLM call."

Why This Change?

The updated wording is more technically accurate and clearer:

• "Before the next LLM call" precisely describes the execution timing
• Removes ambiguity about whether actions run truly "simultaneously" (in parallel threads) vs. sequentially within the same LLM response cycle
• Focuses on the key benefit: reducing round-trips to the LLM
