Artifact path failures told callers to "inspect the reported path" but
reported none: `ArtifactReaderFailure` messages such as
`Artifact path collision: ...` were dropped when converted to
`ArtifactOperationError`, leaving only `{ operation, reason: "path" }`.
Carry the failure message into `details.detail` for artifact tools and
JavaScript application analysis. Name both spellings in case-fold
collisions and include the JSON-escaped input in unsafe and
non-normalized path messages.

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.
