fix(#711): add missing action fields to version/system-prompt/export/init json responses; add contract test assertions

 709. **`render_agents_report_json` and `render_skill_install_report_json` in `commands/src/lib.rs` contained duplicate `"status":"ok"` keys in the same JSON object literal — second key silently overwrites first in serde_json** — found during #708 dogfood sweep on `47c0226a`. Rust `serde_json::json!` macros accept duplicate keys but `serde_json` silently keeps the last occurrence; any consumer relying on the first occurrence gets the wrong value if they are ever different. Fixed by removing the duplicate `status` key from `render_agents_report_json` and `render_skill_install_report_json`. Source: Jobdori dogfood on `47c0226a`, 2026-05-26.
 
 710. **`claw diff --output-format json` missing `action` and `working_directory` fields — both the ok and error paths in `render_diff_json_for` omitted `action` entirely (returning `null` at parse time) and omitted `working_directory`** — dogfooded 2026-05-26 on `8f8eb41e`. Both the clean/changes success path and the no-git-repo error path were missing the two envelope fields that automation uses for routing and provenance. Fix: added `action:"diff"` and `working_directory: cwd.display()` to both branches of `render_diff_json_for`; added contract-test assertions for both fields.

+711. **`version`, `system-prompt`, `export`, and `init` `--output-format json` responses all lacked an `action` field — returned `null` or omitted entirely** — dogfooded 2026-05-26 on `42c17bc4`. All four commands emitted `kind` + `status` but no `action`, making them inconsistent with all other JSON surfaces that include the verb. Fix: added `action:"show"` to `version` and `system-prompt`, `action:"export"` to all three `export` paths, `action:"init"` to `init`; added contract-test assertions for each.
