Python: Add Function Approval UI to DevUI (#1401 )

* ensure function aproval is parsed correctly

* udpate ui, add deployment guide button, other debug panel fixes

* feat(devui): Implement lazy loading architecture with enhanced security and state management

Major architectural improvements to DevUI for better performance, security, and developer experience:

Performance & Architecture:
- Implement lazy loading for entity discovery - entities loaded on-demand instead of at startup
- Add hot reload capability for development workflow via new reload endpoint
- Reduce startup time and memory footprint by deferring module imports

Security Enhancements:
- Remove remote entity loading capabilities (POST /v1/entities/add, DELETE endpoints)
- DevUI now strictly local development tool - no remote code execution
- Add explicit security documentation and best practices in README

Frontend Improvements:
- Migrate to Zustand for centralized state management (replacing prop drilling)
- Add lightweight zero-dependency markdown renderer with code block copy support
- Improve gallery UX with setup instructions modal instead of direct URL loading
- Enhanced message UI with copy functionality and better token usage display

Testing & Quality:
- Expand test coverage for lazy loading, type detection, and cache invalidation
- Add comprehensive tests for new behaviors (+231 lines of test code)
- Improve type safety and documentation throughout

Breaking Changes:
- Remote entity loading via URLs is no longer supported
- Entities must be loaded from local filesystem only

* update ui issues, uupdate test descripion

.NET: [BREAKING] Enable sharing of workflow instances across concurrently executing runs (#1464 )

* refactor: remove unused internals

* feat: Execution Mode for sharing a workflow among concurrent runs

* feat: Update WorkflowHostAgent to support concurrent execution

* Also update AsAgent APIs to support injecting a CheckpointManager and an IWorkflowExecutionEnvironment

* fix: Make Read logic consistent in DeclarativeWorkflowContext

fix: Update WorkflowHostAgent post Checkpointing implementation (#1498 )

WorkflowHostAgent was initially implemented before Checkpointing was available. This meant that in order to support resuming, the WorkflowHostAgent needed to keep the runs around, which broke it when stricter rules about concurrent sharing of workflows during execution were introduced.

This change updates the hosting logic to release the underlying StreamingRun when the RunStreamingAsync or RunAsync are invoked, in favour of keeping the checkpointing information in the WorkflowThread to enable resumption.

- Added 10 comprehensive unit tests validating message routing behavior
- Tests ensure functionality and protect against future refactoring (issue #782)
- Updated code comments to reflect exact-type-matching requirement
