action::Sequence cannot be built directly

Error message

action::Sequence cannot be built directly

What it means

ActionSequence::build() is intentionally unimplementable: action::Sequence exists only as a parsed keymap construct and can never be constructed directly from a single keymap JSON value, so build() always returns this error.
