Merge origin/main into feat/show-reasoning

Browse Source 
Resolves conflicts after main landed the state-machine turn refactor
and the test_runner.py 9-file split:

- nanobot/agent/loop.py: take main's `_state_build`/`_persist_user_message_early`
  flow; restore the `reasoning: bool` parameter on `_build_bus_progress_callback`
  so the loop hook can mark progress as reasoning-channel without coupling to
  the answer stream.
- nanobot/cli/stream.py: keep main's configurable `bot_name`/`bot_icon` header
  while preserving the PR's `transient=True` Live + `self._console` routing
  + `_renderable()` final-render path that fixed TUI duplication.
- tests/agent/test_runner.py was deleted on main and split into 9 focused
  files; relocated all 6 reasoning tests into a new `test_runner_reasoning.py`
  matching the new layout, deduplicated the per-test `ReasoningHook` boilerplate
  through a shared `_RecordingHook` helper.

- Prefer focused patches over broad rewrites

## Modifying CI Workflows
If your PR touches `.github/workflows/`, please keep the CI within
GitHub Actions' free tier:
- Use only standard GitHub-hosted runners (`ubuntu-latest`, `windows-latest`)
- Avoid macOS runners, larger runners (`*-cores`, `*-xlarge`, `*-gpu`),
and self-hosted runners
- Avoid uploading large artifacts or using long retention
- Avoid paid Marketplace actions
If your change genuinely needs to step outside this, please call it out
explicitly in the PR description so it can be discussed before merge.
## Questions?
If you have questions, ideas, or half-formed insights, you are warmly welcome here.

## Model Presets
Use `/model` to inspect the current runtime model:
```text
/model
```
The response shows the current model, the current preset, and the available preset names. `default` is always available and represents the model settings from `agents.defaults.*`.
To switch presets for future turns:
```text
/model fast
/model deep
/model default
```
Preset names come from the top-level `modelPresets` config. Switching is runtime-only: it does not rewrite `config.json`, and an in-progress turn keeps using the model it started with. See [Configuration: Model presets](./configuration.md#model-presets) for setup details.
## Periodic Tasks
The gateway wakes up every 30 minutes and checks `HEARTBEAT.md` in your workspace (`~/.nanobot/workspace/HEARTBEAT.md`). If the file has tasks, the agent executes them and delivers results to your most recently active chat channel.

## Model Presets
Model presets let you name a complete model configuration and switch it at runtime with `/model <preset>`.
Existing configs do not need to change. If you do not set `modelPresets` or `agents.defaults.modelPreset`, nanobot keeps using `agents.defaults.*` exactly as before.
```json
{
"agents": {
"defaults": {
"model": "openai/gpt-4.1",
"provider": "openai",
"maxTokens": 8192,
"contextWindowTokens": 128000,
"temperature": 0.1,
"modelPreset": null
}
},
"modelPresets": {
"fast": {
"model": "openai/gpt-4.1-mini",
"provider": "openai",
"maxTokens": 4096,
"contextWindowTokens": 128000,
"temperature": 0.2,
"reasoningEffort": "low"
},
"deep": {
"model": "anthropic/claude-opus-4-5",
"provider": "anthropic",
"maxTokens": 8192,
"contextWindowTokens": 200000,
"reasoningEffort": "high"
}
}
}
```
`modelPresets` is a top-level object. The keys under it (`fast`, `deep`, `coding`, etc.) are user-defined preset names. Each preset supports:
| Field | Description |
|-------|-------------|
| `model` | Model name to use for this preset. |
| `provider` | Provider name, or `"auto"` to use provider auto-detection. |
| `maxTokens` | Maximum completion/output tokens. |
| `contextWindowTokens` | Context window size used by prompt building and consolidation decisions. |
| `temperature` | Sampling temperature. |
| `reasoningEffort` | Optional reasoning/thinking setting. Provider support varies. |
`default` is reserved and always means the implicit preset built from `agents.defaults.*`; do not define `modelPresets.default`. Use `/model default` to switch back to `agents.defaults.*`.
Set `agents.defaults.modelPreset` to start with a named preset:
```json
{
"agents": {
"defaults": {
"modelPreset": "fast"
}
}
}
```
When `modelPreset` is `null` or omitted, startup uses the implicit `default` preset from `agents.defaults.*`. Runtime changes made with `/model <preset>` are not written back to `config.json`; they affect future turns until the process restarts or another model/config change replaces them.
## Channel Settings
Global settings that apply to all channels. Configure under the `channels` section in `~/.nanobot/config.json`:

"""Tests for Xiaomi MiMo thinking-mode toggle via reasoning_effort.
The hosted Xiaomi MiMo API (api.xiaomimimo.com) accepts
``{"thinking": {"type": "enabled"|"disabled"}}`` in the request body
to toggle reasoning. Source: https://platform.xiaomimimo.com/docs/en-US/api/chat/openai-api
The thinking_type style already exists in _THINKING_STYLE_MAP and
produces exactly this shape, so MiMo just needs to opt in via its
ProviderSpec.thinking_style.
Default thinking behavior per Xiaomi docs:
- mimo-v2-flash: disabled
- mimo-v2.5-pro, mimo-v2.5, mimo-v2-pro, mimo-v2-omni: enabled
Without an explicit reasoning_effort, nanobot must not send the
thinking field so the provider default is preserved (issue #3585).
