Export now diffs the config against defaults and emits
SerializeCBOR -> CompressString (zlib) -> EncodeBase64 with a "!pf1!"
prefix. Import reverses that into a plain table — no loadstring, so a
pasted profile is data and can't execute code. The Decode/Encode button
converts blob <-> editable JSON (SerializeJSON/DeserializeJSON) for
inspection and hand-edits.
Old-format strings still import: standard base64 via DecodeBase64, the
custom LZW decompressor kept import-only, and the resulting Lua source
runs in an EMPTY setfenv sandbox that can only assign its config table.
Decode on a legacy string yields the JSON view, so Encode re-emits it
as a new-format blob (migration path).
Roughly half the paste size of the old LZW format, C-speed instead of
the old bit-string base64 (which froze the client on large configs),
and the format is fully standard — external tools can decode profiles
with stock base64/zlib/CBOR libraries.
Requires ClassicAPI with the SerializeCBOR buffer-growth fix (payloads
over 256 bytes returned nil before it).
