Teknium e946f49ab5 fix(models): add gemini-3.5-flash to Gemini OAuth + API-key pickers (#37046)
* fix(file_tools): block agent writes to ~/.hermes/config.yaml to prevent silent approval bypass

* fix(approval): pair terminal-side gate for ~/.hermes/config.yaml writes

Subway2023's #14639 blocks write_file/patch to ~/.hermes/config.yaml, but
the terminal side was only partially paired: echo>/tee/cp/mv to config.yaml
already tripped the project-config pattern, while `sed -i` and direct edits
slipped through with auto-approve. An unpaired write_file deny is theater per
SECURITY.md — the agent could flip approvals.mode=off via `sed -i` and the
mtime-keyed config cache reloads it mid-session.

config.yaml IS the security policy (approvals.mode/yolo/permanent allowlist
live there), so it warrants real pairing, not a half-door. Add a
_HERMES_CONFIG_PATH fragment mirroring _HERMES_ENV_PATH, fold it into
_SENSITIVE_WRITE_TARGET (covers tee/>/>>/cp/mv), and add sed -i coverage for
both config.yaml and .env. Pins 9 regression tests including no-regression
guards (reads pass, /tmp writes pass).

* chore(release): map Subway2023 for PR #14639 salvage

* fix(models): add gemini-3.5-flash to Gemini OAuth + API-key pickers

#34581 swapped gemini-3-flash-preview -> gemini-3.5-flash in the
OpenRouter and Nous lists but missed the curated Gemini catalogs, so
the Google OAuth (google-gemini-cli) picker still offered the retired
gemini-3-flash-preview slug and gemini-3.5-flash was unselectable.

Per Google's docs gemini-3-flash-preview was renamed to gemini-3.5-flash
and is served via Cloud Code Assist, so this completes the rename for:
- google-gemini-cli (OAuth/Code Assist) picker
- gemini (API-key) picker
- gemini provider default_aux_model

copilot keeps gemini-3-flash-preview (separate backend, own slug).

Model Provider Plugins

Each subdirectory is a self-contained provider profile plugin. The directory layout mirrors plugins/platforms/:

plugins/model-providers/
├── openrouter/
│   ├── __init__.py      # registers the ProviderProfile
│   └── plugin.yaml      # manifest: name, kind, version, description
├── anthropic/
│   ├── __init__.py
│   └── plugin.yaml
└── ...

How discovery works

providers/__init__.py._discover_providers() scans this directory (and $HERMES_HOME/plugins/model-providers/) the first time anything calls get_provider_profile() or list_providers(). Each __init__.py is imported and expected to call providers.register_provider(profile).

User plugins at $HERMES_HOME/plugins/model-providers/<name>/ override bundled plugins of the same name — last-writer-wins in register_provider(). Drop a file there to replace a built-in.

Adding a new provider

  1. Create plugins/model-providers/<your_provider>/__init__.py:

    from providers import register_provider
    from providers.base import ProviderProfile
    
    my_provider = ProviderProfile(
        name="your-provider",
        aliases=("alias1", "alias2"),
        display_name="Your Provider",
        description="One-line description shown in the setup picker",
        signup_url="https://your-provider.example.com/keys",
        env_vars=("YOUR_PROVIDER_API_KEY", "YOUR_PROVIDER_BASE_URL"),
        base_url="https://api.your-provider.example.com/v1",
        default_aux_model="your-cheap-model",
    )
    
    register_provider(my_provider)
    
  2. Create plugins/model-providers/<your_provider>/plugin.yaml:

    name: your-provider-profile
    kind: model-provider
    version: 1.0.0
    description: Short sentence about the provider
    author: Your Name
    

Nothing else needs to change. auth.py, config.py, models.py, doctor.py, model_metadata.py, runtime_provider.py, and the chat_completions transport all auto-wire from the registry.

Non-trivial profiles

Override the ProviderProfile hooks in a subclass for per-provider quirks — see plugins/model-providers/openrouter/__init__.py for build_extra_body and build_api_kwargs_extras examples, and plugins/model-providers/gemini/__init__.py for thinking_config translation.
