Wrap and the Outcome arms gain id slots (unit arms become one-slot id records);
the Python unit-arm codec behaviour is kept on a separate unit union.

leaves.py (string, boolean, bytes, int32, int64, float32, float64, any, list, array, nullable, lazy) held to the
numeric-leaves vectors. Removed: DatabaseEntryField.many, callable codecs and _resolve, the System.Object literal,
the present-nil default, the union's nil pass-through, interop.py's hand-written catalog. A float32 keeps its width
through _pack_tree. Nil is refused unless wrapped in nullable; a default fills only a slot past the payload's end.

The tree walk counted only list, tuple and dict, so a codec whose tree used deque,
mappingproxy or another abc container was unbounded. Every Mapping, Sequence and Set
that is not text or bytes now counts. RecursionError from a user encode or decode,
and from the JSON decoder, reaches the caller as itself with its traceback; only
msgpack's StackError (raised by depth alone) is mapped to the depth refusal.
All commits build.

Removes the equivalent continue in the walk (the stack only ever holds containers).
Pins the exact refusal text on the RecursionError and StackError paths, both sides,
and that the validator receives the written and the decoded value. Every commit builds.

DatabaseEntryField validates its key in one place (0..MAX_SLOT_KEY, no bool), so
database_entry_field, direct construction and field tuples share the rule. A record
shorter than its declared slots no longer refuses a missing slot: the slot is nil
and its default applies, as the C# reference reads it. define_union refuses True
and False as arm keys, each pinned alone. Every commit builds.

Iterative container count over the decoded and the encoded tree (MAX_PAYLOAD_DEPTH,
CultCachePayloadDepthError); msgpack StackError and RecursionError map to the same
refusal. Union decode names an out-of-Int32, non-integer or nil-slots arm as the
reference does. Fixture arms Wrap, Floor, Ceiling; loop over bounds-outcomes.msgpack.
Pins the bool arm-key refusal's callers in the vector loop only; every commit builds.

define_union and define_record_codec share the slot logic of define_database_entry_type
(one record codec); a field takes a codec, many, or a thunk for recursion. Unknown arm
keys are refused naming union and key, never the payload. All commits build.
