refactor: forc-node as lib (#7353)

## Description

This PR fundamentally refactors the `forc-node` plugin architecture by
embedding the Fuel Core node directly as an in-process library rather
than spawning it as a subprocess.
This architectural change modernizes the forc-node plugin and lays the
groundwork for advanced local development features.

## 🔄 Changes Overview

### Core Architectural Changes
- **In-Process Execution**: Fuel Core now runs within the same process
as the plugin, eliminating subprocess management overhead
- **Direct Integration**: Replaced subprocess spawning with direct
library calls to fuel-core
- **Unified Logging**: Consolidated logging and error handling across
all execution modes
- **Improved Configuration**: Enhanced configuration display and
management for better debugging

### Dependency Updates
- Added direct fuel-core dependencies
- Added fuel-core-chain-config for configuration management
- Integrated tracing and tracing-subscriber for improved logging
- Updated Cargo.lock with necessary transitive dependencies

## 💡 Motivation

### Current Limitations
- Subprocess management adds complexity and potential failure points
- Limited ability to extend node functionality
- Difficult to implement advanced features like state forking (planned
feature)

### Benefits of This Change
1. **Performance**: Eliminates IPC overhead and reduces startup time
2. **Reliability**: Direct function calls are more reliable than
subprocess communication
3. **Extensibility**: Easier to add advanced features in future PRs
