compare-web-captures and compare-web-screenshots parsed their arguments as
inline JSON only, unlike every other JSON-input command. Screenshot
artifacts and scenario captures embed base64 PNG bytes, so a typical
viewport screenshot exceeds the command-line length limit (128 KiB per
argument on Linux, 1 MiB total on macOS) and could not be compared from
the CLI at all, while MCP accepts it. A file path was reported as
malformed JSON, and screenshot schema failures returned no issues.
Each argument now accepts inline JSON or a JSON file path through
parseCliJsonInput; file failures keep its path diagnostics, malformed
inline JSON keeps the field issue, and screenshot validation reports
projected schema issues. The tests share one CLI JSON process fixture.

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.
