Module registry 

Plugin registry: the single source of truth for compiled .rhai scripts after discovery. Owns the parsed ASTs + resolved header data. Wrapping a CompiledPlugin in the Segment trait is the RhaiSegment adapter’s job, not this module’s.

PluginRegistry::load walks the discovery order from super::discovery::scan_plugin_dirs, compiles each script, resolves its @data_deps header, and extracts the required const ID declaration. Non-fatal errors (compile failure, unknown dep, id collision) are returned alongside the registry so linesmith doctor can surface them; a single bad plugin does not abort the whole load.

Structs

CompiledPlugin

A single compiled plugin ready to be wrapped by the RhaiSegment adapter.

PluginRegistry

Keyed collection of compiled plugins. Lookup is by id; iteration preserves discovery order. Non-fatal load errors (compile failure, unknown dep, id collision) live alongside the compiled plugins so post-load consumers (e.g. linesmith doctor) can query them at any point without re-running discovery.
