HS: closest parent <sel> traversal (+1 test)

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.

Suite hs-upstream-core/regressions: 10/16 → 11/16.
Smoke 0-195: 162/195 → 163/195.

+### 2026-04-24 — cluster 23 me symbol works in from expressions
+- **COMMIT** — `HS: closest parent <sel> traversal (+1 test)`. `parse-trav` now recognises `parent` as an ident modifier after the `closest` keyword: consumes it and re-invokes itself with kind `closest-parent`, so `closest parent <div/>` produces AST `(closest-parent "div" (me))` instead of `(string-postfix (closest "*" (me)) "parent")` — the latter was the generic trailing-ident-as-unit rule swallowing `parent`. Compiler translates `(closest-parent sel target)` to `(dom-closest (host-get target "parentElement") sel)` so `me` (the element with the `_` attribute) is skipped and only strict ancestors match. Also added `closest-parent` to the `put X into <trav>` inner-html shortcut alongside `next`/`previous`/`closest`. Suite hs-upstream-core/regressions: 10/16 → 11/16. Smoke 0-195: 162/195 → 163/195.

 ### 2026-04-24 — cluster 8 select returns selected text (cherry-picked from worktree)
 - **0b9bbc7b** — `HS: select returns selected text (+1 test)`. Runtime `hs-get-selection` prefers `window.__test_selection` stash and falls back to `getSelection().toString()`. Compiler rewrites `(ref "selection")` to `(hs-get-selection)`. Generator detects `document.createRange() + getElementById(ID).firstChild + setStart/setEnd` and emits a single `host-set!` on `window.__test_selection` with the resolved substring, sidestepping a propagating DOM range/text-node mock. Runner resets `__test_selection` between tests. Suite hs-upstream-select: 3/4 → 4/4.
