createCliResultOutput rendered an explicit null selected by
--filter-output as the empty document {}, the same output it uses when
the selection has no value at all. On the streamed JSON/JSONL path,
a consumer could not distinguish a selected null from a missing field.
Write a selected null as null in streamed JSON and JSONL. This also
preserves an unfiltered top-level null. The {} fallback stays for
undefined, functions and symbols. The --full-output envelope already
carried data: null for a selected null. The --token-count path still
hands results that fit the formatted-string limit back to Incur and
prints 0 for a selected null. Other formats and Incur-owned result
paths are unchanged.
Consumers must accept JSON null for a present null and distinguish it
from a missing selection. Use --full-output if an object envelope is
required. Keeping the old shared {} representation would continue
hiding this distinction.

`--json` / `--format json` always indented its streamed result. Agents and
scripts read REA through pipes and redirects, where indentation carries no
information: on real application results it added 16-45% model tokens
(o200k proxy) and 25-73% bytes. The skill's CLI fallback uses `--json`.
Indent only when stdout is a TTY, as `gh --json` does; piped or redirected
JSON is compact. The JSON value, `jsonl`, `--filter-output`,
`--full-output` and the token-window paths are unchanged. `jq .` restores
indentation for files.

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.
