Optimize performance: reduce allocations, eliminate O(n²) patterns, use Sets

- Replace JSON.parse/stringify clone with type-aware clone (handles RegExp, Date, arrays)
- Replace Object.entries().map() with for loop in nodizeDeep (eliminates throwaway array)
- Hoist key expression regex to module level (avoids recompilation per key)
- Convert skip depth/keys arrays to Sets for O(1) lookups in hot validation loop
- Use Set for node key dedup check instead of Array.includes()
- Optimize pathstr() to build string directly instead of slice/filter/join
- Simplify error array handling in handleValidate (eliminate 4 intermediate arrays)
- Replace keys().filter() with explicit for loops for extra property and element detection
- Fix redundant Object.assign({...spread}, obj) pattern in buildize()
- Consolidate 4 separate Array.splice() calls into single manual shift loop in Rename
- Replace error splice-in-loop with in-place compaction pattern
