[bot] Update Learning Hub for Copilot CLI v1.0.71: /worktree split, voice mode, CLI canvas support

[github-actions]

What new features or changes were found

From the Copilot CLI releases this week (July 9–15, 2026):

v1.0.71-1 (2026-07-14)

• /worktree and /move are now split commands: /worktree creates a new worktree and leaves uncommitted changes behind; /move carries uncommitted changes into the new worktree. This is a behavioral change from the previous behavior where /move was just an alias for /worktree.

v1.0.71-2 (2026-07-15)

• Voice mode (/voice devices): New /voice command for voice input, with /voice devices to choose and persist the microphone.
• Canvas support in CLI: Canvas extensions now work in Copilot CLI (not just the Copilot desktop app).

What sections were updated

copilot-configuration-basics.md

• Fixed the /worktree//move section: corrected outdated description that called /move an alias. Now accurately describes them as distinct commands with different behaviors (v1.0.71+).
• Added /voice and /voice devices documentation (v1.0.71+), placed after the /refine command section.
• Updated lastUpdated to 2026-07-15.

working-with-canvas-extensions.md

• Added a new "Canvas support in Copilot CLI" section noting that canvas extensions now work in CLI sessions (v1.0.71+), not just in the desktop app.
• Updated lastUpdated to 2026-07-15.
