Release v2.3.26

Workflow.yaml now supports all agents.yaml features:

Agent-level features:
- framework (praisonai, crewai, autogen)
- process (sequential, hierarchical, workflow)
- manager_llm for hierarchical process
- function_calling_llm
- max_rpm (rate limiting)
- max_execution_time (timeout)
- reflect_llm, min_reflect, max_reflect
- system_template, prompt_template, response_template
- backstory (alias for instructions)

Step-level features:
- expected_output (like agents.yaml tasks)
- context (task dependencies)
- output_json, output_pydantic (structured output)
- create_directory
- callback
- async_execution

Added 14 new TDD tests for feature parity verification.
All 41 YAML parser tests pass.

+
+- **Session Management**: Automatic `Mcp-Session-Id` handling
+- **Protocol Versioning**: `Mcp-Protocol-Version` header on all requests
+- **Resumability**: SSE stream recovery via `Last-Event-ID`
+- **Security**: Origin validation, DNS rebinding prevention
+- **WebSocket**: Auto-reconnect with exponential backoff
