[$] Radicle: peer-to-peer collaboration with Git

Radicle is a new, peer-to-peer,MIT/Apache-licensed collaboration platform written in Rust and built on topof Git. It adds support for issues and pull requests (which Radicle calls"patches") on top of core Git, which are stored in the Git repositoryitself. Unlike GitHub, GitLab, and similar forges, Radicle is distributed;it doesn't rely on having everyone use the same server. Instead, Radicleinstances form a network that synchronizes changes between nodes.
