HS: Group 11 misc — toggle-var-cycle, closest-to, tailwind class, toggle timing (+3 tests)
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 6m13s
Details

Browse Source 
- parser: `toggle $var between v1 and v2 ...` → `(toggle-var-cycle $var (v1 v2 ...))`
- compiler: emit `(hs-toggle-var-cycle! win var-name values)` for new AST node
- runtime: `hs-toggle-var-cycle!` cycles through a list of values on a variable
- parser: `closest .sel to .target` / `closest #id to .target` / `closest sel to .target`
  now consumes the `to` keyword and parses the target expr instead of defaulting to beingTold
- tokenizer: `read-class-name` handles backslash escapes and allows `(`, `)`, `&`
  chars so Tailwind classes like `group-[:nth-of-type(3)_&]:block` tokenize correctly
- platform.py: `domListen` drives async result via `_driveAsync` after `cekCall`
- test: fixed-time toggle asserts `.foo` IS present after click (toggle started, 10ms window open)
- generate-sx-tests.py: aligned MANUAL_TEST_BODIES for timed toggle with corrected assertion
