Import custom agents when importing workflows

[Copilot]

The import-workflow prompt imports workflows from other repositories but doesn't handle custom agents referenced by those workflows.

Changes

• Added Step 3: Detects custom agent references via engine.agent field and imports array, fetches .agent.md files from source repository .github/agents/ directory
• Updated Step 4: Preserves custom agent references in imported workflow frontmatter
• Updated Step 8: Includes custom agent files in PR and lists them in description

Implementation Details

Custom agents can be referenced two ways:

# Via engine.agent field
engine:
  agent: technical-doc-writer  # → .github/agents/technical-doc-writer.agent.md

# Via imports array  
imports:
  - .github/agents/my-agent.agent.md

The workflow now checks both locations, fetches referenced files from the source repository, and saves them to .github/agents/ in the target repository.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/github/gh-aw/git/ref/tags/v0.45.3
  • Triggering command: /usr/bin/gh gh api /repos/github/gh-aw/git/ref/tags/v0.45.3 --jq .object.sha (http block)
• https://api.github.com/user
  • Triggering command: /usr/bin/gh gh api user --jq .login (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
