Optimize getter performance by caching memoization symbols
- Pre-compute and cache memoization symbols during FastGetBuilder construction
- Eliminates repeated Symbol.for() calls identified as bottleneck in CPU profiles
- Reduces symbol lookup overhead in hot path for read-only instance getters
- Add getter-optimization benchmark for targeted performance validation
- All existing tests pass, maintaining API compatibility

Fix performance regressions with lazy symbol caching
- Replace eager symbol pre-computation with lazy caching
- Fix inconsistency between cached and Symbol.for() usage
- Update outerClosureStatements to use Symbol.for() in generated code
- Update fast-instantiator to use Symbol.for() consistently
- Maintain symbol caching benefits while eliminating instantiation overhead
