Is your feature request related to a problem? Please describe

The current implementation:

• Passes multiple parameters to every serialization method
• Mixes read and write state in a single context
• Has redundant indirections and flag checks
• Lacks fast paths for common primitive types

Describe the solution you'd like

Implement performance optimizations:

• Separate ReadContext and WriteContext to eliminate unnecessary state
• Add fast paths for primitives (bool, int*, float*, string)
• Inline common operations for compiler optimization
• Add fast paths for common collection types ([]int, []string, etc.)
• Optimize struct field serialization with direct memory access

Benefits

• Reduced method call overhead
• Better CPU cache utilization
• Faster serialization for common types
• More efficient memory access patterns
