Testing / test (push) Failing after 10m21s
refactor: split compat into package, harden serve proxy (v0.9.3)
- compat.py → compat/ package: auth.py (auth-field normalizers),
  commands.py (command-format shims), __init__.py (re-exports)
- Add _auth_0_9_3 transformer: normalizes pubkey to lowercase before auth
  so clients < 0.9.3 sending uppercase hex are accepted
- adapt_auth() now called before auth check in serve.py; command extracted
  after adapt_auth so future transformers can rename commands safely
- serve.py: deduplicate _recv_exact (import from client), unify
  resp/resp_payload across Windows/Unix branches, require lowercase hex
  pubkey (re.fullmatch), reorganize imports, drop unused os import
- client.py: move payload/framed construction inside branches (remote path
  no longer serializes JSON it never uses); fix _is_valid_key_spec
  operator precedence; import MAX_MSG_BYTES from version_manager
- auth.py: narrow except clause (ValueError instead of bare Exception)
- Bump version 0.9.2 → 0.9.3

"""
Command-format shims — applied to clean_msg (protocol fields already stripped)
before forwarding to the native host, and to responses before sending back.
Add one entry per breaking command-format change:
("X.Y.Z", request_fn, response_fn)
- request_fn(msg: dict) -> dict or None
- response_fn(resp: bytes, command: str) -> bytes or None
Entries must stay in ascending version order.
adapt_request walks forward (oldest first); adapt_response walks backward.
Current baseline: 0.9.3 — no command-format shims needed yet.
