Remove test-runtime workflow and dispatch targets

[Copilot]

Removes the test-runtime workflow that demonstrated dispatch-workflow safe output capability, along with its target workflows add-name and add-emojis.

Files removed:

• .github/workflows/test-runtime.md + .lock.yml - Main workflow demonstrating dispatch-workflow
• .github/workflows/add-name.yml - Dispatch target (echo name input)
• .github/workflows/add-emojis.yml - Dispatch target (echo emoji input)

These were test fixtures with no other dependents in the repository.

Original prompt

@copilot Remove test-runtime workflow and the workflows it references, plus their ymls
