[PROD-003] .NET service and scheduled-worker entrypoint

[ktalpay]

Task ID: PROD-003
Lane: dotnet
Status: merged
Agent: dotnet-agent
Depends on: PROD-002

Goal:
Add the first .NET production-runtime parity slice: an installable and directly runnable .NET service/scheduled-worker entrypoint shape equivalent to the Python operator path.

Scope:

• Provide a .NET executable/worker entrypoint for one-cycle execution.
• Support operator-style command usage without source edits.
• Add config validation entrypoint/stub sufficient for later production config work.
• Do not implement full source ingestion, DB insert, or parser parity in this task.
• Document how the .NET entrypoint fits the production parity contract.

Acceptance:

• .NET command path is explicit.
• Scheduling/service usage is documented without implying unsupported DB ingestion parity.
• Tests cover entrypoint/help/config-validation boundary where practical.
• No production credentials.
• No generated artifacts.
