// Package processors defines feedkit's generic processor abstraction and registry.
//
// Processors are optional pipeline stages that can transform, drop, or reject
// events before dispatch to sinks.
//
// Registry provides name-based construction so daemons can assemble processor
// chains without embedding switch statements in wiring code.
//
// Example:
//
//	reg := processors.NewRegistry()
//	reg.Register("dedupe", dedupe.Factory(10_000))
//	reg.Register("normalize", func() (processors.Processor, error) {
//	    // import "gitea.maximumdirect.net/ejr/feedkit/processors/normalize"
//	    return normalize.NewProcessor(myNormalizers, false), nil
//	})
//
//	chain, err := reg.BuildChain([]string{"dedupe", "normalize"})
//	if err != nil {
//	    // handle wiring error
//	}
//
//	p := &pipeline.Pipeline{Processors: chain}
