Update default models to claude-opus-4-6, remove unused ToolAccess

- Default model for both foreground and background agents: claude-opus-4-6
- Background agent params now match foreground (max_tokens: 8192, thinking_budget: 2000)
- Remove unused ToolAccess enum and tool_access field
- Fix README and config.example.toml config structure (model under [agents.foreground] not [general])
- Bump version to 0.1.0-rc.11

 ## Custom System Prompts
 
 You can extend Codey's system prompt by creating `SYSTEM.md` files that are automatically appended to the base prompt. These files are loaded from two locations (in order):
