giles e4773ec336 HS: split type-check (predicate) from type-assert (:) — +5 comparisonOperator ...

Last commit's `hs-type-check` rewrite collapsed predicate and assertion
into one runtime fn that always raised on mismatch. That fixed `: Type`
but broke `is a Type` / `is not a Type` (which need a bool):

  null is a String       expected true,  got nil   (raised)
  null is not a String   expected false, got true  (default boolean)

Restored the split. Parser now emits `(type-assert ...)` for `:` and
keeps `(type-check ...)` for `is a` / `is not a`. Runtime adds:
- `hs-type-check`        — predicate, never raises (nil passes)
- `hs-type-check-strict` — predicate, false on nil
- `hs-type-assert`       — value or raises
- `hs-type-assert-strict` — value or raises (also raises on nil)
Compiler maps `type-assert` / `type-assert-strict` to the new runtime fns.

comparisonOperator 74/83 → 79/83 (+5: `is a/an`, `is not a/an` four tests
plus a fifth that depended on them). typecheck stays 2/5 (no regression).
