Moved `discountRegex` and `roundOffKeywords` to module scope to avoid re-creation on every `sanitizeParsedData` call. This is a safe optimization to reduce overhead. Benchmark showed negligible improvement (~4%), likely due to V8 regex literal optimizations, but this change ensures optimal behavior and cleaner code.

💡 What:
Moved the
discountRegexandroundOffKeywordsdefinitions from inside thesanitizeParsedDatafunction to the module scope (top-level constants).🎯 Why:
Previously, these were being re-created every time
sanitizeParsedDatawas called (which happens for every receipt processed). While V8 optimizes regex literals well, defining them as module-level constantsDISCOUNT_REGEXandROUND_OFF_KEYWORDSguarantees they are initialized only once, avoiding any potential reallocation overhead and adhering to best performance practices.📊 Measured Improvement:
Benchmark runs (500,000 iterations) showed a slight fluctuation in execution time (approx 1636ms vs 1565ms), indicating the improvement is within the noise margin (likely < 5%). This suggests the JS engine was already optimizing the literal efficiently, but the change makes the optimization explicit and robust. Correctness was verified with existing logic tests.
