gh-attachments: GitHub media uploads

Native GitHub CLI 2.99.0+ with --attach listed in the specific command’s help, an authenticated account and repository push access. Official release support is GitHub.com and GitHub Enterprise Cloud; no CLI extension is required for this native flag.

Provide the local image/video path and intended repository, issue/PR and action. Confirm gh version and the chosen command’s help before use. The supported commands are gh issue create/edit/comment and gh pr create/edit/comment; --attach uploads the media and inserts or rewrites its URL in the body. Confirm the target, content and visibility before invoking a posting or editing command.

This sends media to GitHub and creates or edits externally visible content. Public-repository uploads can be accessed without authentication; private/internal uploads are viewable by people with repository access according to GitHub’s docs. Do not infer support in older gh versions or on Enterprise Server. The CLI supports image/video uploads, not every attachment type the browser accepts. An issue-create command can exit nonzero after creating an issue with partial upload success; inspect the returned URL/result before retrying.
