PINK Phase 3 (G4): stream wiring + recovery + reconcile gate

Browse Source 
pink_direct.py:
- connect(): set_seed_capital + REST account snapshot for crash recovery
- _run_account_stream(): BingxUserStream -> kernel.on_account_event()
  FILL_SETTLED folds K; ACCOUNT_UPDATE stores E-facts + runs reconcile;
  reconcile ERROR -> _enter_frozen=True (ENTERs blocked, exits always free)
  FUNDING_FEE folds K-funding_net
- _unsafe_entry_reason(): checks _enter_frozen first
- step(): capital from available_capital (E rules when present, K fallback)
- _venue_http_client() / _venue_ws_url() helpers

test_account_reconcile_faults.py (Gate G4):
  fee/funding/rounding -> WARN; unexplained -> ERROR
  crash-recovery sequence; exit-never-frozen invariant

109/109 total offline tests pass.

"""Gate G4: Reconcile fault-injection + recovery tests.
Proves:
- Fee / funding / rounding → WARN (not ERROR)
- Unexplained capital divergence → ERROR
- Position count mismatch → ERROR (via Python AccountProjectionV2)
- ERROR freezes new ENTERs in the runtime freeze flag
- K≈E after sync → unfreezes, OK
- Crash-recovery sequence: seed → E-seed → reconcile OK → stream fills
- Exits never blocked (only ENTERs frozen)
