💡 What: Replaced O(N) indexOfObject array lookup for tracking global identifiers with an O(1) dictionary (globalNames).
🎯 Why: The original array-based lookup performs poorly (O(N²)) when parsing files with many unique global variables, causing parsing times to scale quadratically.
📊 Impact: Improves parsing performance drastically for files with many globals.
🔬 Measurement: Verified using npm run bench:luast and checking large file parse times with globals enabled.

This replaces the `indexOfObject` array lookup for tracking global identifiers
with an O(1) dictionary (`globalNames`), which drastically improves parsing
performance when scanning files with many unique global variables.
