* fix(hopper): diagnose MCP provider failures with stage, state, and request context
* fix(hopper): retain health at the actual provider lifecycle boundary
* test(hopper): distinguish socket loss from later observed process exit
* test(hopper): cover observed exit separately from socket-first replies

* 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.
