refactor(domain): split error taxonomy into thematic modules (#636)

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.
