Integrate session checkpoint into Resume AI CLI flow

[Copilot]

Resuming an AI CLI session now offers an immediate checkpoint prompt instead of requiring a separate transient action. This folds checkpoint capture into the resume workflow and removes the extra dedicated menu entry.

• Resume flow

  • Route C-c a R through a small wrapper around ai-code-cli-resume
  • Preserve existing prefix-arg behavior for backend-specific resume flows
  • Prompt after resume: Print AI session checkpoint?
  • Reuse the existing ai-code-session-checkpoint implementation when the user confirms

• Transient menu

  • Keep Resume AI CLI in the AI CLI session section
  • Remove the standalone AI session checkpoint entry from Other Tools

• Targeted test updates

  • Cover resume-menu wiring to the new wrapper
  • Cover checkpoint prompt accept/decline behavior
  • Cover removal of the old transient entry

(defun ai-code-cli-resume-with-session-checkpoint (&optional arg prompt-for-checkpoint)
  (interactive (list current-prefix-arg t))
  (ai-code-cli-resume arg)
  (when (and prompt-for-checkpoint
             (y-or-n-p "Print AI session checkpoint? "))
    (ai-code-session-checkpoint)))

Pull request overview

This PR integrates session checkpoint capture into the “Resume AI CLI” workflow, so resuming a backend session can immediately prompt the user to request a checkpoint, and removes the now-redundant standalone checkpoint menu entry.

Changes:

• Add ai-code-cli-resume-with-session-checkpoint, an interactive wrapper around ai-code-cli-resume that optionally prompts Print AI session checkpoint? and reuses ai-code-session-checkpoint.
• Update the AI CLI session transient so R routes through the new wrapper, and remove the P “AI session checkpoint” entry from Other Tools.
• Expand ERT coverage for menu wiring, prompt accept/decline behavior, and removal of the old transient entry.

Delay checkpoint until resume picker finishes

For picker-based resume flows, confirming here sends the checkpoint before the session has actually been chosen. For example, ai-code-opencode-resume documents that the CLI presents an interactive list of past sessions and then calls ai-code-backends-infra--cli-show-resume-picker (ai-code-opencode.el lines 85-100), and GitHub Copilot does the same picker poke (ai-code-github-copilot-cli.el lines 119-122). Because this wrapper asks immediately after ai-code-cli-resume returns, the checkpoint prompt is typed into the terminal picker instead of an active resumed AI prompt, so the new integrated checkpoint flow fails for those backends.
