### Breaking Changes

- **Agent class moved to `@mariozechner/pi-agent-core`**: The `Agent` class, `AgentState`, and related types are no longer exported from this package. Import them from `@mariozechner/pi-agent-core` instead.

- **Transport abstraction removed**: `ProviderTransport`, `AppTransport`, `AgentTransport` interface, and related types have been removed. The `Agent` class now uses `streamFn` for custom streaming.

- **`AppMessage` renamed to `AgentMessage`**: Now imported from `@mariozechner/pi-agent-core`. Custom message types use declaration merging on `CustomAgentMessages` interface.

- **`UserMessageWithAttachments` is now a custom message type**: Has `role: "user-with-attachments"` instead of `role: "user"`. Use `isUserMessageWithAttachments()` type guard.

- **`CustomMessages` interface removed**: Use declaration merging on `CustomAgentMessages` from `@mariozechner/pi-agent-core` instead.

- **`agent.appendMessage()` removed**: Use `agent.queueMessage()` instead.

- **Agent event types changed**: `AgentInterface` now handles new event types from `@mariozechner/pi-agent-core`: `message_start`, `message_end`, `message_update`, `turn_start`, `turn_end`, `agent_start`, `agent_end`.

### Added

- **`defaultConvertToLlm`**: Default message transformer that handles `UserMessageWithAttachments` and `ArtifactMessage`. Apps can extend this for custom message types.

- **`convertAttachments`**: Utility to convert `Attachment[]` to LLM content blocks (images and extracted document text).

- **`isUserMessageWithAttachments` / `isArtifactMessage`**: Type guard functions for custom message types.

- **`createStreamFn`**: Creates a stream function with CORS proxy support. Reads proxy settings on each call for dynamic configuration.

- **Default `streamFn` and `getApiKey`**: `AgentInterface` now sets sensible defaults if not provided:
  - `streamFn`: Uses `createStreamFn` with proxy settings from storage
  - `getApiKey`: Reads from `providerKeys` storage

- **Proxy utilities exported**: `applyProxyIfNeeded`, `shouldUseProxyForProvider`, `isCorsError`, `createStreamFn`

### Removed

- `Agent` class (moved to `@mariozechner/pi-agent-core`)
- `ProviderTransport` class
- `AppTransport` class
- `AgentTransport` interface
- `AgentRunConfig` type
- `ProxyAssistantMessageEvent` type
- `test-sessions.ts` example file

### Migration Guide

**Before (0.30.x):**
```typescript
import { Agent, ProviderTransport, type AppMessage } from '@mariozechner/pi-web-ui';

const agent = new Agent({
  transport: new ProviderTransport(),
  messageTransformer: (messages: AppMessage[]) => messages.filter(...)
});
```

**After:**
```typescript
import { Agent, type AgentMessage } from '@mariozechner/pi-agent-core';
import { defaultConvertToLlm } from '@mariozechner/pi-web-ui';

const agent = new Agent({
  convertToLlm: (messages: AgentMessage[]) => {
    // Extend defaultConvertToLlm for custom types
    return defaultConvertToLlm(messages);
  }
});
// AgentInterface will set streamFn and getApiKey defaults automatically
```

**Custom message types:**
```typescript
// Before: declaration merging on CustomMessages
declare module "@mariozechner/pi-web-ui" {
  interface CustomMessages {
    "my-message": MyMessage;
  }
}

// After: declaration merging on CustomAgentMessages
declare module "@mariozechner/pi-agent-core" {
  interface CustomAgentMessages {
    "my-message": MyMessage;
  }
}
```
