This commit completes all remaining Sprint 1 tasks from the project analysis:
**MCP RPC Timeout Protection**
- Add configurable `rpc_timeout_secs` field to McpServerConfig
- Implement operation-specific timeouts (10s-120s based on method type)
- Wrap all MCP RPC calls with tokio::time::timeout to prevent indefinite hangs
- Add comprehensive test suite (mcp_timeout.rs) with 5 test cases
- Modified files: config.rs, remote_client.rs, presets.rs, failover.rs, factory.rs, chat_app.rs, mcp.rs
**Async Migration Completion**
- Remove all remaining tokio::task::block_in_place calls
- Replace with try_lock() spin loop pattern for uncontended config access
- Maintains sync API for UI rendering while completing async migration
- Modified files: session.rs (config/config_mut), chat_app.rs (controller_lock)
**Dependency Updates**
- Update tokio 1.47.1 → 1.48.0 for latest performance improvements
- Update reqwest 0.12.23 → 0.12.24 for security patches
- Update 60+ transitive dependencies via cargo update
- Run cargo audit: identified 3 CVEs for Sprint 2 (sqlx, ring, rsa)
**Code Quality**
- Fix clippy deprecation warnings (generic-array 0.x usage in encryption/storage)
- Add temporary #![allow(deprecated)] with TODO comments for future generic-array 1.x upgrade
- All tests passing (except 1 pre-existing failure unrelated to these changes)
Sprint 1 is now complete. Next up: Sprint 2 security fixes and test coverage improvements.
