* refactor(domain): split error taxonomy into thematic modules 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. * refactor(runtime): name all silent catch causes without changing diagnostics Bind cause in every bare catch and unhandled rejection across src/. Real failures preserve the cause for logging; best-effort cleanup carries an explicit comment. Caller-visible and Evidence strings are byte-identical to before.
