Missing / Incorrect Definition

Several declarations in src/lib/esnext.*.d.ts are missing JSDoc @param and @returns annotations.

Examples include:

• Error.isError
• Date.toTemporalInstant
• Atomics.pause
• Map/WeakMap getOrInsert*
• Array.fromAsync
• Uint8Array.fromHex

Adding the missing annotations improves consistency and IntelliSense documentation without affecting behavior.

Sample Code

const ok = Error.isError(new Error("x"));

const instant = new Date().toTemporalInstant();

Atomics.pause(10);

const map = new Map<string, number>();
map.getOrInsert("a", 1);

const arr = await Array.fromAsync(Promise.resolve([1, 2, 3]));

Uint8Array.fromHex("deadbeef");

// These APIs currently work correctly, but some declarations
// are missing JSDoc @param/@returns annotations used for
// IntelliSense documentation consistency.
