Subject: chore(just): Add `verify-standalone` recipe
X-Git-Url: http://internal-gitweb-vhost/-script/src/example_cli/database/enum.AnyDatabase.html?a=commitdiff_plain;h=37411ea4713a8706c3af9beda24494f99649fed7;p=bdk

chore(just): Add `verify-standalone` recipe

Packages a crate and builds the packaged copy outside the workspace, so
sibling workspace crates resolve from crates.io instead of local paths.

This catches crates that accidentally depend on unreleased changes in
other crates of the same workspace. Extra args are passed to `cargo build`.

Added alias `vs` for quick access.
