* feat(cli): add JSON Lines output for row-oriented results (#5487)
- Support opt-in JSON Lines format (--format jsonl) for row-oriented results and collection views with clear record boundaries
- Preserve stable source identities and stream records deterministically line-by-line
- Emit final coverage and limitation metadata as a distinct line with https://rea.dev/schemas/jsonl-coverage-v1.json to prevent confusion with data rows
- Distinguish error outputs with https://rea.dev/schemas/jsonl-error-v1.json
- Reject non-row-oriented results that lack record boundaries with an unreadable_output error
- Document JSON Lines streaming conventions in docs/cli.md
- Add boundary tests covering empty results, multiline strings, partial coverage, large fields, and non-row rejection
* fix(cli): preserve diagnostics, provenance, and nested collections in JSONL
* fix(cli): frame classified failures and reject unrepresented JSONL facets

`--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.
