Optimize uniq function for better performance

[Ben1524]

Improve the performance of the unique function by:

1. Pre-allocating map capacity with len(s) to avoid frequent map resizing
2. Pre-allocating result slice capacity with len(s) to reduce append overhead
3. Reducing the number of traversals performs well under the condition of a large number of elements

These changes maintain the original behavior (preserving element order) while reducing memory allocation operations, especially effective for large slices (100k+ elements) with benchmark showing ~25% speedup.

No breaking changes, the function signature and output order remain unchanged.

Hi, thanks for the PR, currently this code is ran very infrequently (every a couple minutes) and input size is constrained by the # of open connections your system can take, so I doubt this is going to be the bottleneck on application performance.

But otherwise lgtm

Thanks for your review! I understand your point about the execution frequency and input size. Just wanted to optimize it as a precautionary measure. Glad you think it looks good otherwise. Let me know if there's anything else needed.
