chore: drop a trailing blank line so cargo fmt --check passes

PR Check has failed on "Check formatting" since 2026-08-05 because
src/commands/initiatives.rs ends with an extra blank line. It is the only
formatting diff in the tree, and it is unrelated to the fixes in this
branch — happy to split it out if you would rather take it on its own.
