Core I2P package providing fundamental interfaces, version information, and entry points to essential I2P services.

This package contains the foundational components that form the public API of I2P, including:

• I2PAppContext: Central context for accessing I2P services and configuration
• Version information: Build version, update checking, and release management
• Core interfaces: Fundamental abstractions used throughout the I2P codebase
• Service locators: Entry points for accessing router and application services

With a few exceptions, this package and all others in i2p.jar are maintained as a stable API for use by apps, clients, and plugins. The classes in this package provide the primary means for external applications to interact with the I2P network.

Key Usage:

• Applications should obtain an I2PAppContext to access I2P services
• Version checking and update management is handled through this package
• Core interfaces define contracts for I2P-compatible implementations
