Implement the server-side session handlers (create, retrieve, send message,
stream events, list) with in-memory storage and LLM generation, wire them
into the router replacing not_implemented stubs, add run_chat_via_server
CLI function with SSE streaming, and add mode dispatch so `arc llm chat
--mode server` delegates to the API server.

Enables `arc models test` to work in server mode by adding an API
endpoint that sends "Say OK" (max_tokens=16, 30s timeout) to a model
and reports pass/fail. Dry-run mode returns synthetic "ok" status.

Commands can now delegate to a running Arc API server instead of
executing in-process. Adds ExecutionMode, ServerDefaults, and
ClientTlsConfig to cli.toml parsing with CLI flag > config > default
precedence. The models list command fetches from GET /models when in
server mode, with mTLS client certificate auth when [server.tls] is
configured.

The extract_status_fields function recognized "outcome" as a field for
detecting status JSON objects but never read its value — LLM responses
like {"outcome": "fail", "failure_reason": "tests failed"} were silently
ignored and the outcome was always Success.
Now extract_status_fields reads the outcome field to set the node status
and failure_reason to populate the failure detail. Also adds a fallback:
if no routing directives are found in the response text, the handler
reads status.json from the sandbox CWD (written by agents that prefer
file output over inline JSON). Response text always takes priority.
