Update RST documentation for PR#10 multi-database and threading features

[Copilot]

Comprehensive update to all RST documentation files to reflect the new features introduced in PR#10 and improve overall documentation quality.

Major Changes

New Features Documented:

• Multi-database endpoint support: Configuration now supports both single database (config['db'] as dict) and multiple databases (config['db'] as list) for automatic load balancing
• Threading model support: Added documentation for both threaded and non-threaded deployment models to optimize for different server architectures
• Enhanced connection handling: Updated examples and configuration guides to reflect improved connection pooling and management
• Transaction control: Documented the Handler.commit() method for manual transaction management with autocommit=False connections

Documentation Structure Improvements:

• intro.rst: Rewritten module description emphasizing load balancing capabilities and architecture benefits
• config.rst: Added comprehensive multi-database configuration examples, threading model selection, and deployment scenarios
• examples.rst: New examples showing multi-database setups, transaction management, and non-threaded configurations for process-based servers
• design.rst: Complete architectural overview covering threading models, load balancing, and performance considerations
• build.rst: Modernized build instructions with virtual environments, modern Python tooling, and comprehensive testing guides
• api.rst: Reorganized API reference with better categorization and method documentation
• index.rst: Enhanced with quick start guide and improved table of contents organization

Quality Improvements:

• Consistent RST formatting and syntax throughout all files
• Updated code examples with proper module imports (from pgdbpool import pool as dbpool)
• Clear deployment recommendations for different web server configurations (Apache, Gunicorn, uWSGI)
• Improved technical terminology and descriptions
• Added performance optimization guidelines and memory usage considerations

Configuration Examples

The documentation now includes comprehensive examples for various deployment scenarios:

# Multi-database configuration with load balancing
config = {
    'type': 'threaded',
    'db': [
        {'host': 'primary-db.example.com', 'name': 'myapp', ...},
        {'host': 'replica-db.example.com', 'name': 'myapp', ...}
    ],
    'groups': {
        'read_pool': {'connection_count': 15, 'autocommit': True},
        'write_pool': {'connection_count': 10, 'autocommit': False}
    }
}

Version Information

Updated CHANGELOG.md to reflect version 1.0rc1 features and the evolution from the previous 0.99 release, highlighting the significance of the multi-database support as a major milestone toward the 1.0 release.

These documentation updates ensure that users can fully leverage the new multi-database capabilities and choose the appropriate threading model for their deployment architecture, while maintaining backward compatibility with existing single-database configurations.
