## `fabro provider login`

Re-authenticating with LLM providers previously required re-running the full `fabro install` wizard. You can now re-authenticate with any provider independently using `fabro provider login`.

```bash
fabro provider login --provider openai
```

For OpenAI, this launches the browser-based OAuth PKCE flow with an automatic fallback to manual API key entry. All other providers prompt for an API key with validation. Later releases moved these credentials into the server-owned secret store.

## Auto-detect default LLM provider

The CLI now checks which providers have API keys configured and automatically selects the best available one, using precedence order Anthropic > OpenAI > Gemini. Previously, running commands without an explicit `--provider` flag always defaulted to Anthropic, which caused errors for users who only had OpenAI or Gemini keys configured.

## `fabro wait`

A new `fabro wait` subcommand blocks until a workflow run reaches a terminal state and exits with a code reflecting the outcome — analogous to `docker wait`. Accepts a run ID prefix or workflow name, with an optional `--timeout` flag and `--json` output mode for scripting.

```bash
fabro wait abc123 --timeout 300
```
