Include selected region in Emacs runtime debug prompts

[Copilot]

ai-code-debug-emacs-runtime previously only sent the freeform issue description to the AI session. When debugging keybindings or interactive behavior, that omitted the exact Elisp/config snippet the user had selected.

• Runtime debug prompt context

  • Extend ai-code--emacs-runtime-debug-prompt to accept optional selected-region context.
  • Append a Selected region: block to the generated prompt when a region is active.
  • Include git-relative line location metadata when available, matching existing prompt conventions elsewhere in the package.

• Command behavior

  • Update ai-code-debug-emacs-runtime to capture the active region before assembling the confirmation prompt.
  • Preserve existing behavior when no region is selected.

• Focused coverage

  • Add a targeted ERT case verifying that the runtime debug prompt includes:
    • the selected region label
    • region location info
    • the selected Elisp snippet itself

Example of the prompt shape after this change:

Runtime issue description:
C-c x runs the wrong interactive command

Selected region:
ai-code.el#L10-L11
(global-set-key (kbd "C-c x") #'wrong-command)

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:

• dl.google.com

• elpa.gnu.org
  • Triggering command: /usr/bin/emacs emacs -Q -batch --eval (progn (require 'package) (setq package-archives '(("gnu" . "REDACTED") ("nongnu" . "REDACTED") ("melpa" . "REDACTED"))) (package-initialize) (package-refresh-contents) (dolist (pkg '(transie get mand-not-found/ the (dns 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)
