- Block deletion of a model provider when it is referenced by any agent,
returning an error that lists the agent names so the user knows what to unlink first
- When a provider's api_url or api_key is updated, automatically propagate
the new credentials to all dependent agents: updates env_json in the database
and patches on-disk config files (Claude Code settings.json, Gemini settings.json,
Codex auth.json + config.toml, OpenCode auth.json) using the same field names
and structure as the agent settings UI
- Fix error message display in provider dialogs for both Tauri and web transports,
which throw plain objects rather than Error instances
