This PR optimizes the listVariables and listWriteableVariables methods in NUTClient.ts. The original implementation used Object.fromEntries(res.map(...)), which creates an intermediate array of arrays (entry pairs) before building the final object. This intermediate array is unnecessary and can be avoided by populating the object directly within a for...of loop.

Measured performance improvement:

  • Baseline (original): ~820ms for 10,000 iterations of 100 entries.
  • Optimized: ~558ms for the same workload.
  • Total Improvement: ~32% reduction in execution time.

Functional correctness was verified with a standalone script ensuring all edge cases (missing keys, missing values) are handled identically to the original code.


PR created automatically by Jules for task 1403194372722262313 started by @thib3113

Replace `Object.fromEntries(res.map(...))` with a single-pass `for...of` loop to build the result object.
This optimization avoids the creation of intermediate arrays of entry pairs, reducing memory allocations and improving CPU efficiency.

- File: `src/NUTClient.ts`
- Improvement: ~32% speedup in object construction from response lines.
- Verification: Measured with benchmark script and verified functional correctness.
