feat(mc): make the F2 menu overridable via local.mc.menu

Expose the user menu as a `types.lines` option instead of a baked source
file. The shipped menu is a `mkBefore` definition (not a `default`, which a
consumer definition would drop), so `local.mc.menu = "…"` appends entries
after the baseline and `lib.mkForce "…"` replaces it wholesale.

`ini` stays a baked source file: it is section/key=value, so append-to-extend
risks duplicate keys — not a safe override path.
