What's new in 2.0.0

• CC Pocket is now Pairlet. The new name appears throughout the app, with a one-time notice explaining the change.
• A shorter computer command: use pairlet with the same subcommands as cc-pocket-daemon. The legacy command remains available.
• Updated website and help links for pairlet.org, with support for both the old and new GitHub repository addresses.
• Improved discovery of standalone OpenCode CLI installations when the daemon runs in the background.
