Show HN: Copy code from Neovim with file paths and repo URLs for web AI (github.com)

Neovim plugin copy_with_context.nvim that copies code with context: file paths, line numbers, and repository permalinks. Makes web AI coding assistants way more useful since they know exactly where code lives in your project.

v3 adds GitHub/GitLab/Bitbucket URL generation with commit SHAs. Zero dependencies.
