Add a common cross-exchange interface (/mcp) over the integrated venues
(deribit, hyperliquid):
- get_instruments: uniform schema where each row carries its own
`exchange`, `fees` (maker/taker, live from Deribit, null where the
venue has no per-instrument schedule) and `history_start` (listing
date, live from Deribit creation_timestamp), plus type/tick_size and a
lossless `native` blob. Optional `exchange` filter; fan-out otherwise.
- get_historical: generalized to {exchange, instrument, interval,
start_date, end_date}, returning a single chosen venue's candles.
Consensus merge stays available on /mcp-cross.
New: routers/unified.py, exchanges/cross/instruments.py (normalizers),
UnifiedClient in cross/client.py, schemas in cross/tools.py. Deribit
get_instruments now also surfaces maker/taker_commission and
creation_timestamp (additive).
Retire Bybit and Alpaca from the API surface: move clients, routers,
settings classes and their tests under old/ (history preserved via
git mv); drop them from the builder, /mcp-cross dispatch and symbol_map.
Bybit remains a public funding/OI data source in sentiment (not the
trading client). IBKR is intentionally excluded from /mcp for now.
Docs: rewrite API_REFERENCE.md (remove Bybit/Alpaca, document /mcp,
clarify that data_timestamp is injected globally by middleware).
Tests: add unified-interface coverage; update cross/settings/builder/boot
tests for the reduced venue set. Fix a pre-existing flaky assertion in
the Hyperliquid signing test (r/s use eth_utils.to_hex like the official
SDK, so a leading zero byte yields <66 chars ~1/256 of the time).
323 passed, ruff clean.

DeribitSettings ora supporta coppie credenziali distinte per testnet e
mainnet via DERIBIT_CLIENT_ID_TESTNET/_LIVE e DERIBIT_CLIENT_SECRET_TESTNET/_LIVE.
Le coppie env-specifiche prevalgono sulla coppia base
DERIBIT_CLIENT_ID/DERIBIT_CLIENT_SECRET (mantenuta per backward compat).
build_client risolve la coppia giusta tramite settings.deribit.credentials(env);
ValueError esplicito se nessuna coppia configurata per l'env richiesto.
+4 test (legacy single, per-env, override, missing). Fix anche isolation
da .env reale via monkeypatch.chdir(tmp_path).

Task 6.7: porting alpaca da services/mcp-alpaca a src/cerbero_mcp.
client.py + leverage_cap.py copiati 1:1 (default cap 1 cash).
tools.py: 17 tool senza ACL/Principal/audit. Router /mcp-alpaca con 18
route (env_info + 17 tool). Builder branch alpaca: paper=(env=="testnet"),
api_key viene da settings.alpaca.api_key_id. Test client + leverage_cap
migrati (15 test alpaca pass). Test builder con stub SDK alpaca-py.
