refactor(perf): Optimize hot paths to reduce GC pressure and improve runtime (#4121)

- Replace O(n²) indexOf dedup in getUnique() with Set-based O(n)
- Replace JSON.stringify/parse tooltip change detection with lightweight fingerprint
- Replace Math.min/max(...spread) with manual loops to prevent stack overflow
- Replace new RegExp() per-key loop in tplProcess with single replace pattern
- Merge double filter/forEach in findClosest into single loop
- Replace Object.keys() in hot paths with for...in or direct property access
- Convert Cache storage from plain object to Map (avoids delete deoptimization)
- Remove unnecessary spread copies and closure allocations in tooltip/domain
- Replace chained map/filter/reduce with single loops and Object.assign
