refactor(apps,tests): migrate applications and tests to unified resource system

Complete the migration by updating main applications, integration tests,
and examples to use the new capability-based resource management system:

Main Library (wrt):
- Integration of all subsystems using unified resource patterns
- Enhanced WebAssembly execution with capability-based memory management
- Improved resource limits and safety compliance features
- Standardized prelude and public API using safe_managed_alloc\! patterns

WRT Daemon (wrtd):
- Capability-aware daemon implementation with bounded resource usage
- Enhanced neural network integration with resource budget enforcement
- Improved configuration management using unified allocation patterns
- Better error handling and recovery mechanisms

WRT Dagger (wrt-dagger):
- Modern resource management for WebAssembly analysis tools
- Enhanced integration with the unified memory system

Integration Tests (wrt-tests):
- Comprehensive test coverage for capability-based resource management
- Enhanced formal verification tests with bounded resource scenarios
- Improved memory safety and atomic operation testing
- Better component model integration tests

Examples:
- Updated all examples to demonstrate proper resource management patterns
- Enhanced ASIL-B compliance examples with capability verification
- Improved neural network examples with bounded tensor operations
- Better demonstration of safety-critical execution patterns

This completes the comprehensive migration to unified resource management,
ensuring consistency, safety, and maintainability across the entire
WebAssembly runtime ecosystem while maintaining ASIL compliance.
