[GuideLLM Refactor] utility package updates, rewrites, and tests expansion needed for the other, refactored packages

[markurtz]

Summary

Introduces a comprehensive utilities infrastructure to support distributed processing, inter-process communication, and statistical analysis for the GuideLLM framework. The changes include new modules for encoding/serialization, messaging systems, statistical computations, and various utility mixins while removing deprecated functionality and improving code organization.

Details

• Added messaging infrastructure (messaging.py): Inter-process communication abstractions supporting queue-based, pipe-based, and manager-based messaging with configurable encoding and serialization
• Added encoding utilities (encoding.py): High-performance message encoding/decoding with Pydantic model support, configurable serialization strategies (dict/sequence), and binary encoding (msgpack/msgspec)
• Added statistical analysis (statistics.py): Comprehensive statistical computation tools including distribution summaries, percentiles, running statistics, and specialized request timing analysis
• Added registry system (registry.py): Dynamic object registration and discovery with auto-discovery capabilities for extensible plugin architectures
• Added Pydantic utilities (pydantic_utils.py): Polymorphic model serialization, registry integration, and standardized base model classes
• Added console utilities (console.py): Rich console integration with status tracking, colored output, and progress indicators
• Added synchronization utilities (synchronous.py): Async-compatible wrappers for threading/multiprocessing synchronization primitives
• Added singleton patterns (singleton.py): Thread-safe and basic singleton implementations for resource management
• Added utility functions (functions.py): Safe arithmetic operations, timestamp formatting, and defensive programming utilities
• Added mixin classes (mixins.py): Reusable mixins for metadata extraction and object introspection
• Added auto-importer (auto_importer.py): Automatic module importing for dynamic class discovery
• Enhanced text utilities: Added format_value_display() function for consistent metric formatting and improved documentation
• Removed deprecated code: Deleted dict.py module with recursive_key_update() and camelize_str() function from text.py
• Updated imports: Comprehensive reorganization of __init__.py exports to reflect new utilities structure

Test Plan

• Full unit tests added and passing
