perf: remove raw field from timeline items to reduce payload size

Remove the `raw` field that was duplicating provider data in timeline
items, reducing WebSocket payload sizes by 64-85%:
- session_state: ~320KB → ~48KB
- agent_stream_snapshot: ~320KB → ~114KB

Changes:
- Remove raw from AgentTimelineItem, AgentStreamEvent, AgentPermissionRequest
- Remove raw assignments from claude-agent.ts and codex-agent.ts
- Remove provider_event handling from stream.ts (only used for Codex raw)
- Update tests to reflect new behavior
