feat(Project): Update dependencies and synchronize Element submodule with ecosystem enhancements

This commit integrates critical updates across the Land monorepo to advance the code editor's reliability, monitoring capabilities, and streaming support within the declarative effects-based architecture.

- **Dependency Updates**: Downgraded `reqwest` to v0.12.28 with the `stream` feature enabled and added `tokio-stream` to support enhanced streaming capabilities for the Vine gRPC communication layer between Mountain and Cocoon. This prepares the infrastructure for real-time data flows required by the SynchronizationService and HealthService implementations.
- **Element Submodule Sync**: Updated the Element submodule to commit 2a7386b3, incorporating major enhancements across core components. Air now uses `tonic::codec::Streaming` for improved gRPC compatibility, Cocoon introduces HealthService with Effect-TS based monitoring, Mountain strengthens IPC with full TauriIPCServer implementation, and Wind adds HealthService integration via Tauri commands. These changes fulfill architectural contracts defined in Common and improve cross-component communication reliability.

Collectively, these updates reinforce Land's production readiness by enhancing fault tolerance, observability, and the consistency of the effects-based ecosystem.
