Land the Plane - Finish-Line Protocol

Turn "the code works" into "the work is shipped." This is the user-invocable form of AGENTS.md's "Landing the Plane" → Mode B protocol (non-isolated agents and sessions). Run it whenever $ARGUMENTS names a scope or branch that is ready to close out. Work is NOT complete until the push is verified.

Isolated worktree workers (agent frontmatter declares isolation: worktree) use Mode A instead — commit on the assigned branch and report to the orchestrator, do not push. See AGENTS.md; do not apply this skill there.
