Add copilot --remote panel to Chapter 01 visual quickstart

[Copilot]

The Chapter 01 visual quickstart comic had no panel covering the --remote flag or /remote slash command, despite the README already containing a full tip section on remote sessions.

Changes

• docs/content.yaml — New panel entry for Chapter 01 (between the slash-commands panel and the chapter-end panel) with speech bubble and two copyable terminal commands:

  copilot --remote  # start with remote access
  > /remote         # or enable it mid-session
  

• docs/chapter-01.html — Hand-inserted matching <figure> (badge 10); renumbered the "On to Chapter 02!" panel badge 10 → 11. Links deep into the existing ## 💡 Tip: Control Your CLI Session from Web or Mobile README section.

Notes

• Reuses ch01-commands.webp (session-control theme) — swap in a dedicated ch01-remote.webp later with no other changes needed.
• HTML was edited by hand; content.yaml is the authoritative source and the HTML will be regenerated correctly when the visual-quickstart-generator build tool is next run.
