What I'm doing wrong?
Is it because copilot was installed from snap store?

Reproduce the failure with `copilot plugin marketplace browse awesome-copilot` using the snap-installed `/snap/bin/copilot`, after checking `copilot --version` and the available Git commands. Investigate the reported missing `git remote-https` and template path, then verify that browsing the marketplace completes without the warning or clone error.
