parse-trav recognises `parent` as an ident modifier after the
`closest` keyword — consumes it and re-invokes with kind
`closest-parent`, producing AST `(closest-parent "div" (me))` instead
of the generic trailing-ident-as-unit shape
`(string-postfix (closest "*" (me)) "parent")`.
Compiler translates `(closest-parent sel target)` to
`(dom-closest (host-get target "parentElement") sel)` so `me` is
skipped and only strict ancestors match. `closest-parent` also
joined the `put X into <trav>` inner-html shortcut alongside
next/previous/closest.
