Copilot CLI v1.0.19-0: Session & Plugin Fixes

TL;DR

• IDE auto-connect now skips when session is already active elsewhere
• Slash command timeline entries now show command names for clarity
• Plugin hooks with missing execute permissions now work on macOS
• Custom agents properly restore when resuming sessions

Improved

• IDE auto-connect skip — No longer attempts to reconnect when your session is already in use by another client, reducing connection conflicts.
• Slash command timeline context — Timeline entries now display command names (e.g., "Review", "Plan") alongside entries for better visibility into what you ran.

Fixed

• Plugin hook permissions on macOS — Plugin hook scripts missing execute permissions now run correctly instead of failing silently.
• Custom agent restoration — Custom agents properly restore when resuming a session where the agent display name differs from its filename.

Update with: npm install -g @github/copilot-cli@latest
