v0.7.0

## Behavior changes
- **Device selection:** `mobilerun run` uses `-d`, then `ANDROID_SERIAL`, then the only online device. With several devices attached and none selected, it now stops with an error instead of using the first device in `adb devices`.
- **Tool calls:** FastAgent runs only the first `<function_calls>` block of a reply. Later blocks are ignored, and the model is told so. Tool-call markup before that block makes the reply malformed. After a failed call, the rest of the block is skipped.

## Highlights
- **Gemini API:** `gemini-4-argon` is available.
- **Anthropic OAuth:** supports `--stream`.
- **Usage:** Gemini usage now counts thinking tokens as output.
- **Portal:** if the Portal accessibility service is turned off during a run (e.g. Play Protect force-stops Portal), mobilerun re-enables it right away and restores the Portal keyboard. `setup --path` waits on `/ping` and no longer launches Portal.
- **Cloud:** requires mobilerun-core-local 0.6.3, which reads cloud UI trees correctly with mobilerun-sdk 5.x/6.x and no longer retries tap/type calls.
