feat: layer runtime and model selection across conversation, project and global

- Store runtime selection as { provider?, model? } layers and resolve them per field (conversation -> project -> global); drop the legacy auto provider. - Migrate stored selections (database v49) and clear deleted profile ids. - Re-resolve selections in Main per request and at queue dispatch. - Add ProjectRuntimeSelector and a two-column RuntimeModelPicker; manage link opens model connections; restore per-runtime default model tabs. - Stop duplicating trusted instructions and history across OpenCode, Continue and DeepSeek Harness runtimes. - Document the layered design, global provider removal plan and planned purpose-specific models.
