master f5b5f24d95 Add StellaOps.Workflow engine: 14 libraries, WebService, 8 test projects 
Extract product-agnostic workflow engine from Ablera.Serdica.Workflow into
standalone StellaOps.Workflow.* libraries targeting net10.0.

Libraries (14):
- Contracts, Abstractions (compiler, decompiler, expression runtime)
- Engine (execution, signaling, scheduling, projections, hosted services)
- ElkSharp (generic graph layout algorithm)
- Renderer.ElkSharp, Renderer.ElkJs, Renderer.Msagl, Renderer.Svg
- Signaling.Redis, Signaling.OracleAq
- DataStore.MongoDB, DataStore.PostgreSQL, DataStore.Oracle

WebService: ASP.NET Core Minimal API with 22 endpoints

Tests (8 projects, 109 tests pass):
- Engine.Tests (105 pass), WebService.Tests (4 E2E pass)
- Renderer.Tests, DataStore.MongoDB/Oracle/PostgreSQL.Tests
- Signaling.Redis.Tests, IntegrationTests.Shared

Tutorial 7: Shared Support Helpers

When building many workflows for the same domain (e.g., 50+ policy change workflows), extract reusable components into a support helper class.

What to Extract

Component Example
Address constants LegacyRabbitAddress, HttpAddress — centralized routing
Workflow references WorkflowReference — for SubWorkflow/ContinueWith targets
Payload builders Static methods returning WorkflowExpressionDefinition
State initializers Base state + override pattern
Flow extensions Extension methods on WorkflowFlowBuilder<T> for common sequences
