Malte UblandClaude Opus 5.5 70c39cca49 Keep frozen records frozen for untyped code and ignore refused sloppy writes ...

Object.freeze of a fresh record or array literal now sets the native
frozen bit instead of compiling to the literal, so an untyped reference to
the value sees it frozen: Object.isFrozen answers true and strict-mode
writes throw Node's TypeErrors.

Untyped property writes in sloppy-mode code (IrModule.sloppyDynWrites,
decided per write by isStrictCode) call scr_dyn_key_set_sloppy and its
computed form, which drop exactly the TypeError a refused assignment raises
(a read-only or frozen property, a non-extensible object, a frozen array
element) while a setter's exception still propagates. Computed-write
dispatch helpers are shared only by writes of the same mode.
