Move each error family out of domain/errors.ts into its own module (base, core, provider selection/adapter, browser observation, artifact, evidence, unknown registry, hopper, configuration) and relocate AnalysisErrorProjection to analysisErrorProjection. Migrate all 162 importers to the owning modules and delete errors.ts. No re-export shims; behavior is unchanged.
