* fix(js): real structuredClone so CryptoKey and buffers survive cloning
structuredClone was JSON.parse(JSON.stringify), which silently drops
ArrayBuffer and TypedArray to {}. A cloned CryptoKey also lost its WeakMap
entry, so crypto.subtle.sign/encrypt/deriveBits threw "Argument is not a
valid CryptoKey" on the clone.
Replace the JSON fallback with a recursive cloner covering ArrayBuffer,
TypedArray, DataView, Map, Set, Date, RegExp, Error, and plain objects,
with cycle and own symbol-keyed property handling. CryptoKey opts in via a
clone hook (keyed by Symbol.toStringTag) that rebuilds the key through
makeKey, so the clone re-enters the WeakMap and stays usable.
Fixes#389.
* fix(js): structuredClone handles DataView and rejects functions and symbols
The TypedArray branch called value.slice(), which DataView lacks, so
cloning any DataView threw TypeError, a new crash in the buffers
category this feature targets. Copy the underlying buffer slice over
the view range and wrap a fresh DataView.
The function/symbol rejection lived after the primitive early-return
and was dead code, so functions and symbols were passed through by
reference instead of throwing DataCloneError (HTML structured clone).
Check first and throw.
Register ArrayBuffer, TypedArray, and DataView in the seen map so
repeated references share one clone, and move the cycle check up.
