Tests using `run("expr", {locals: {x}})` were being translated to SX like
(let ((x val)) (eval-hs "expr") (assert= it EXPECTED))
That never worked: `it` is bound inside eval-hs's handler closure, not in
the outer SX scope, so the assertion errored "Undefined symbol: it".
Meanwhile `x` (bound by the outer let) wasn't reachable from the
eval-expr-cek'd handler either, so any script referencing `x` resolved
via global lookup — silently yielding stale values from earlier tests.
New `eval-hs-locals` helper injects locals as fn parameters of the
handler wrapper:
(fn (me arr str ...) (let ((it nil) (event nil)) <compiled-hs> it))
It's applied with the caller's values, returning the final `it`. The
generator now emits `(assert= (eval-hs-locals "..." (list ...)) EXP)`
for all four expect() patterns when locals are present.
New baseline: 1,055 / 1,496 pass (70.5%, up from 1,022 / 1,496 = 68.3%).
29 additional tests now pass — mostly `pick` (where locals are the
vehicle for passing arr/str test fixtures) plus cascades in
comparisonOperator, asExpression, mathOperator, etc.
Note: the remaining `pick` wins in this batch also depend on local
edits to lib/hyperscript/parser.sx and compiler.sx (not included here;
they're intertwined with pre-existing in-flight HS runtime work).
