Feedback: default footers a bit large

[dsyme]

Feedback from @lucabol that the default footers are a bit long and a bit spammy, githubnext/agentics#252

---

There is a already mention at the top of the comment that it was generated by Repo Assist, the phrasing at the bottom of each comment seems a bit too much to my taste. Or at least remove the instructions on how to install it as they are easily obtainable.

Generated by [Repo Assist](https://github.com/lucabol/JediTestRepoV2/actions/runs/22859678670) · [◷](https://github.com/search?q=repo%3Alucabol%2FJediTestRepoV2+%22gh-aw-workflow-call-id%3A+lucabol%2FJediTestRepoV2%2Frepo-assist%22&type=issues)

To install this [agentic workflow](https://github.com/githubnext/agentics/tree/346204513ecfa08b81566450d7d599556807389f/workflows/repo-assist.md), run

gh aw add githubnext/agentics/workflows/repo-assist.md@346204513ecfa08b81566450d7d599556807389f

My comment is about the default experience of people using Repo Assist, as such a thick footer reduces the number of comments that can be seen in one screen (and feels marketish). My comment wasn't about my particular needs. But good to know that it can be customized and overall not important enough to be reopened.

I think we should remove the "To install this agentic workflow, run

gh aw add githubnext/agentics@3462045"

We don't need ads on every comment.

1. Add a documention-link: URL field to the frontmatter
2. Change footer to one line

> Generated by [Repo Assist](markdown-link) [run](run-link) [documentation](documentation-link).

The documentation field would be suppressed if documentation-link is not present

Our template are static right now and we need to add a conditional rendering to support this. Why not override the messages in repo assist itself? You could give it more personality.

Fair enough, can do
