Add install guidance to recompile agentic workflows

[Copilot]

Bug Fix

What was the bug?

Installed Autoloop repos could lack agent-facing instructions to recompile generated workflow artifacts after editing .github/workflows/*.md, leading to stale .lock.yml / integration files and APM Self-Check failures.

How did you fix it?

• Install instructions

  • Added a new install step that appends an Agentic Workflows section to AGENTS.md.
  • Notes that repos using CLAUDE.md or COPILOT.md should receive the same guidance.

• Install integration coverage

  • Updated the install integration prompt for the new step numbering.
  • Added phase-1 assertions that generated repo instructions include the required compile and commit guidance.

## Agentic Workflows

After modifying any `.md` workflow file under `.github/workflows/`, always recompile:

```bash
gh aw compile
apm compile

Commit the regenerated .lock.yml and integration files together with your changes.
