claw-code/tests/test_exec_route_bootstrap_output_format.py

"""Tests for --output-format on exec-command/exec-tool/route/bootstrap (ROADMAP #168).

Closes the final JSON-parity gap across the CLI family. After #160/#165/
#166/#167, the session-lifecycle and inspect CLI commands all spoke JSON;
this batch extends that contract to the exec, route, and bootstrap
surfaces — the commands claws actually invoke to DO work, not just inspect
state.

Verifies:
- exec-command / exec-tool: JSON envelope with handled + source_hint on
  success; {name, handled:false, error:{kind,message,retryable}} on
  not-found
- route: JSON envelope with match_count + matches list
- bootstrap: JSON envelope with setup, routed_matches, turn, messages,
  persisted_session_path
- All 4 preserve legacy text mode byte-identically
- Exit codes unchanged (0 success, 1 exec-not-found)
