Adds a new phase to the current milestone's roadmap. Appends the next integer phase by default; with --after N inserts a decimal phase (N.1, N.2, ...) right after phase N for urgent mid-milestone work, without renumbering. Use to extend the roadmap with planned work, or to slot in urgent work discovered during execution. Creates the phase directory and ROADMAP.md entry; does not plan or commit.
