optimized pick() to eliminate intermediate array allocation

[khresth]

Description

Optimized the pick() function to improve performance by eliminating intermediate array allocations. The original implementation used keys.map() to create an array of [key, value] tuples, then converted it to an object via Object.fromEntries(). This created temporary data structures on every invocation.

The new implementation directly constructs the result object in a single loop, reducing memory allocations and iteration overhead. Since pick() is called twice per API request (for query params and body params), this optimization should improve performance across SDK operations.

How was this change tested?

• Automated test (unit, integration, etc.)
• Manual test (provide reproducible testing steps below)

bash
node node_modules\jest\bin\jest.js ./test

Pull request overview

This PR optimizes the internal pick() helper in src/utils.ts to reduce per-call allocations/iteration overhead by replacing the keys.map() + Object.fromEntries() approach with a single-loop object construction. This supports overall SDK request performance since pick() is used when building request query/body params.

Changes:

• Reimplemented pick() to build the result object via a for...of loop instead of creating intermediate [key, value] tuples.
• Introduced a direct assignment-based implementation returning the accumulated object.

[Copilot]

pick() now uses (base as any)?.[key], introducing an any escape hatch that removes type safety and can mask real type errors. Consider restructuring the types so the loop can assign without any (e.g., build into a Partial<Pick<...>>/record shape and cast once at the end, or adjust the base parameter type to explicitly allow nullish values and keep the indexed access typed).
