Fix 'no rule to make target monitor-dev' error in quickstart

[Copilot]

make quickstart fails when user enables monitoring setup because cmd_setup.go invokes make monitor-dev, which doesn't exist in the Makefile. The correct target is monitor-up.

Changes

• cmd/jan-cli/cmd_setup.go: Replace monitor-dev → monitor-up
• .gitignore: Add cmd/jan-cli/jan-cli binary
