v1.0.4

Bug Fixes

Block Inheritance with Nested Blocks (#1)

• Fixed block inheritance to work correctly with blocks defined inside control structures
• Blocks inside {% if %}, {% for %}, {% apply %} and other control structures are now properly recognized and can be extended
• Added recursive block collection to ensure all blocks are found regardless of nesting level

Template Loading

• Fixed relative path resolution for template loading
• Fixed template fallback mechanism to only execute for not found errors (not for syntax errors)

Performance Improvements

Zero Allocation Optimizations

• Implemented comprehensive zero-allocation rendering path
• Added buffer pooling to reduce memory allocations
• Optimized string handling during tokenization with global string cache
• Improved expression evaluation to reduce allocations
• Added node pooling for commonly used node types

New Performance Features

• Introduced zero_alloc_tokenizer.go for high-performance tokenization
• Added extensive buffer pool implementation for efficient memory reuse
• Implemented expression pooling to reduce GC pressure

Code Quality Improvements

• Fixed indentation and formatting issues
• Renamed parser_include.go to parse_include.go (fixing typo)
• Removed redundant optimization benchmark files
• Consolidated optimization implementations

Testing

• Added comprehensive tests for nested block scenarios
• Added relative path resolution tests
• Added benchmarks for buffer pooling and expression evaluation
