ethernet c35a6d65c9 merge: upstream/main into ethie/pm-clean
Bring in 597 upstream commits while preserving the branch's intentional
divergence (pm store, MSIX desktop, Termux removal).

Resolution notes:
- local_runtime/local-models cluster (30 both-added files): took upstream's
  evolved version — our side was a stale feat-merge snapshot with zero
  post-merge commits, and our non-conflicted importers were verified against
  upstream's exports.
- install scripts (install.ps1/install.sh/setup-hermes.sh): kept our staged
  pm-store bootstrappers (upstream still ships the old monolithic installer).
- Deleted-by-us files (node-bootstrap.sh, install_ps1 tests, termux.md):
  kept deleted — the pm store replaced that machinery.
- runtime_repair.py: kept ours (pm-based), restored upstream's managed_uv.py
  which surviving upstream files still import.
- Core files (run_agent, update_cmd, main.py, hermes_constants, estop,
  aux_client, browser_tool, desktop entry, config_defaults): per-file merges
  combining both sides' features (upstream fleet-wide estop, PID-identity
  daemon kill, editable-install guard; our utf-8-sig sweep, stable channel,
  PYTHONPATH desktop entry).
- Desktop/i18n: took upstream's flag-gated local-models components; merged
  both sides' i18n keys; merged run-electron-builder.mjs and notifications
  tests keeping both sides' tests.
- pyproject.toml: upstream's expanded exclude-newer list + our
  google-cloud-pubsub entry; uv.lock regenerated from the merged pyproject.

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.
