Add github.actor to GitHub context prompt

[Copilot]

Adds github.actor to the GitHub context injected into agent prompts, eliminating the need for agents to call get_me to identify who triggered the workflow.

Changes

• pkg/workflow/prompts/github_context_prompt.md: Added github.actor and simplified the context template to use markdown bullet points instead of XML tags
• pkg/workflow/github_context_test.go: Updated tests to verify github.actor presence

Result

Agents now receive:

<github-context>
The following GitHub context information is available for this workflow:
- **actor**: octocat
- **repository**: owner/repo
- **issue-number**: #123
...
</github-context>

Original prompt

Update the github context prompt to include the github.actor so that the user does not have to query get_me

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/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)
