Lattice

Added

• Added typed PacketEvents listener registration with Lattice-owned unregister handles, listener priority, packet event wrappers, and a safe API handle for version-specific access.
• Added command argument builders for custom parsers, completions, and greedy final string arguments.
• Added command help entries for flattened command-tree diagnostics and plugin-owned help commands.
• Added integration detail metadata, hook diagnostics, command-tree diagnostics, and isolated-mode active JDBC health reporting.
• Added README examples of public plugins built on Lattice: Tabular, Junction, and Onboard.

Changed

• PacketEvents binding now reports API class/version details when available.
• Runtime diagnostics now include hooks and richer integration, command, and storage details.
• DefaultIntegrationManager closes AutoCloseable integration services during runtime shutdown.

Fixed

• PacketEvents bootstrap now catches linkage failures in the same defensive style as PlaceholderAPI.
• Isolated storage diagnostics now report active JDBC connection health instead of only registered providers.

Compatibility

• Existing new CommandArgument<>(name, type, required) calls continue to work.
• Existing new CommandDiagnostics(name, aliases, description, permission) calls continue to work.
• Existing PacketEventsService#api() callers continue to work; new code should prefer apiHandle() and typed listener registration.
