Constant DOCS_URL 

pub const DOCS_URL: &str = "https://github.com/kbrdn1/gwm-cli/tree/main/docs";

Canonical documentation URL opened by the . key (issue #233).

Derived from the crate’s repository (Cargo.toml) so a fork points at its own docs without a patch — there is no standalone docs site deployed yet, so the MVP target is the docs tree on the repo’s default branch. A [docs] config override is a possible follow-up.
