Fix eval PR numbers and negative trigger prompts

- Replace non-existent PR numbers (#34000, #33500, #33000, #34100)
  with real merged PRs (#34024, #34727, #31202, #28713, #34723)
- Add "in dotnet/maui" to all prompts to prevent agent asking for repo
- All PRs verified as real merged PRs with actual code changes
