[Feature Request]: Add a plugin/extension system to allow third-party modules to extend Celtrix functionality

[divyanshim27]

Summary

Celtrix currently appears to implement a fixed set of features with no mechanism for external contributors or users to extend its functionality through plugins or modules. For an OS-level or platform project aiming to be open and composable, a well-defined plugin/extension API is essential for long-term growth and community adoption.

Problem

• There is no documented plugin interface, hook system, or module registry in the codebase.
• All functionality must be contributed directly to the core repository, creating a monolithic architecture that is harder to maintain as scope grows.
• Contributors with specialized use cases (custom integrations, domain-specific extensions) have no clean path to extend Celtrix without modifying core code.
• An extensible architecture is a prerequisite for building a healthy ecosystem around the project.

Impact

• Growth is bottlenecked by the core maintainers' bandwidth since all extensions must go through main.
• The project cannot serve niche use cases without accumulating scope in core.
• Contributors who want to add specialized features have no clear contribution path.

Proposed Solution

1. Define a Plugin interface with lifecycle hooks:

   interface CeltrixPlugin {
     name: string;
     version: string;
     onInit?: (context: CeltrixContext) => void;
     onShutdown?: () => void;
     // extend with domain-specific hooks as needed
   }

2. Create a PluginRegistry that loads and manages plugins, validates their interface compliance, and calls lifecycle hooks at the appropriate points.
3. Document the Plugin API with a PLUGIN_DEVELOPMENT.md guide.
4. Create a reference plugin demonstrating the full plugin lifecycle as a concrete example for third-party developers.

Additional Notes

• I will design the plugin system to be non-breaking — the core system works identically with zero plugins registered.
• Could you assign this to me?
