Yogthos fe3fdf6b9c Transients: mutable backing instead of copy-on-write 
The Chez port had landed transients as copy-on-write — each conj!/assoc!/etc.
rebuilt the whole persistent collection. Semantics were right but a transient
vector was O(n^2) to build (the persistent vector is a flat array, so every
conj! copied it); maps/sets were ~O(n log n) since the HAMT only path-copies.
This restores the Janet host's approach: true mutable backing, snapshot once on
persistent!.

  vec : a growable Scheme vector (capacity + fill count); conj!/pop! amortized
        O(1), persistent! hands off the buffer (exact fit) or trims once.
  map : a Chez hashtable keyed by key-hash/jolt= (value equality, nil-safe);
        persistent! folds it into a pmap.
  set : a Chez hashtable; persistent! folds into a pset.
  cow : fallback for anything else (e.g. a sorted coll) keeps the old
        copy-on-write path, preserving jolt's superset.

get/count/contains?/nth see through each representation. Building a 400k vector
went from minutes (quadratic) to ~50ms (linear). assoc! keeps the variadic
dangling-key nil-pad on both vectors and maps. test/chez/transient-test.ss pins
the invariants and the linear-time property; wired in as `make transient`.
