Add provider/model selection for schedules and workspace fetch debug logging

- Unify resolveProviderAndModel across CLI and server, supporting
  provider/model syntax (e.g. codex/gpt-5.4) for agent runs and schedules
- Add --provider flag to schedule create CLI and both MCP schedule tools
- Add structured debug logging to workspace fetch hydrate, sidebar
  refresh, and real-time update paths
- Update orchestrate skill references
