HTTP 500 (Internal Server Error) was not triggering model fallback,
causing agents to fail outright instead of trying the next candidate.
This is inconsistent with TRANSIENT_HTTP_ERROR_CODES which already
includes 500. Aligns the direct status check with that constant.

The Claude CLI backend uses `--output-format json`, which produces no
stdout until the entire request completes. When session context is large
(100K+ tokens) or API response is slow, the no-output watchdog timer
(max 180s for resume sessions) kills the process before it finishes,
resulting in "CLI produced no output for 180s and was terminated" errors.
Switch to `--output-format stream-json --verbose` so Claude CLI emits
NDJSON events throughout processing (init, assistant, rate_limit, result).
Each event resets the watchdog timer, which is the intended behavior —
the watchdog detects truly stuck processes, not slow-but-progressing ones.
Changes:
- cli-backends.ts: `json` → `stream-json --verbose`, `output: "jsonl"`
- helpers.ts: teach parseCliJsonl to extract text from Claude's
`{"type":"result","result":"..."}` NDJSON line
Note: `--verbose` is required for stream-json in `-p` (print) mode.

When the CLI backend output mode is "text", sessionId was hardcoded to
undefined. This caused the fallback chain to store the OpenClaw internal
UUID as the CLI session ID. On resume, --resume was called with the
wrong UUID, resulting in "No conversation found with session ID".
Return resolvedSessionId instead of undefined so the correct CLI session
ID is persisted and resume works correctly.
codex-cli lacks systemPromptArg, so the system prompt is never
serialized into argv — making the not-toContain assertion pass
vacuously even on pre-fix code. Switch to claude-cli which defines
systemPromptArg ("--append-system-prompt") and add a positive
assertion that the user-supplied prompt IS present in argv.
