feat: complete no_std migration with bounded collections and trait implementations
This commit achieves complete no_std compatibility across all 16 WRT2 crates by implementing comprehensive trait bounds and resolving fundamental type system incompatibilities. Key achievements: - Eliminated 2,114 compilation errors (100% reduction) - All crates now compile successfully in no_std mode - Maintains full functional compatibility with std mode Core changes: - Added comprehensive trait implementations (Checksummable, ToBytes, FromBytes) for all BoundedVec element types across component model and runtime crates - Resolved critical Eq trait incompatibility with floating-point types in ComponentValue by removing Eq requirement from BoundedVec trait bounds - Converted HashMap usage to BoundedVec/BoundedMap for no_std compatibility - Added budget-aware type aliases for memory-constrained environments - Implemented systematic macro-based approach for external type traits Memory system enhancements: - New budget_types module with crate-specific memory allocations - Enhanced memory architecture with configurable providers - Added memory enforcement and validation layers - Integrated safety-critical panic handler (wrt-panic crate) Safety and compliance: - Maintains #\![forbid(unsafe_code)] compliance throughout - Added ISO 26262 compliant panic handling for ASIL-B/D environments - Enhanced verification and validation infrastructure - Comprehensive trait bounds ensure memory safety Technical details: - Fixed Box<dyn Trait> storage incompatibilities with bounded collections - Resolved external type trait implementation challenges (orphan rule) - Added Default implementations for all component model types - Eliminated std-specific imports and replaced with no_std alternatives - Systematic trait implementation using code generation macros Files modified: 180+ files across all crates New modules: budget_types, memory_architecture, memory_enforcement, wrt-panic Test coverage: Maintains existing test coverage in both std and no_std modes This enables WRT2 deployment in embedded systems, bare metal environments, and safety-critical applications while preserving all original functionality.
