Route ordinary CLI results through the bounded JSON writer after command registration, including managed member inspection. Remove JavaScript-specific output plumbing while preserving filters, envelopes, cancellation, and failure exits.
Measure formatted UTF-16 expansion before Incur token counting and return resource_constraint above the runtime string limit, with recovery guidance.
Validate output above the real V8 string limit by SHA-256 and exercise the compiled managed provider. Clean-worktree validation: npm run check; 76 focused tests passed, with 2 optional-provider skips; test discovery passed.
Fixes#1371.
