Pull request overview

Introduces a unified PluginSpec contract (plugin refactor R2) so services and components share one spec shape, while keeping ServiceSpec/ComponentSpec as back-compat subclasses and adding tests to lock in the new behavior.

Changes:

• Added aegis.core.plugin_spec.PluginSpec + PluginKind as the unified spec layer.
• Refactored ServiceSpec/ComponentSpec to subclass PluginSpec and updated component registry field names to the canonical dependency fields.
• Added contract/regression tests ensuring defaults, alias properties, and registry shape invariants.
