Class EventIndexKeyAttribute

Namespace
DotBoxD.Plugins.Indexing
Assembly
DotBoxD.Plugins.dll

Marks an event property the host keeps a dispatch index for. DotBoxD owns predicate lowering and exposes index metadata on the plugin manifest (IndexedPredicates); this attribute is how a host declares which of those property paths it can actually serve from an equality/range bucket. EventIndexMatcher<TEvent> reads it (once, with a compiled getter) and ignores manifest predicates whose path is not an index key, leaving them to the verified IR.

Promoted to the framework as the first-class declaration surface (issue #50) so any host can opt into index-based prefiltering without reimplementing the matcher. It stays purely declarative: a property the host does not mark is simply never served from the index.
