E84 (Parallel I/O) is fundamentally per-load-port: each port has its
own ten-wire handshake with the AMHS. Earlier revisions modeled it
as a single equipment-wide FSM; this commit refactors to a per-port
store, so multi-LP tools can run independent handshakes in parallel.
Public API change in EquipmentDataModel:
E84StateMachine e84; -> removed
E84PortStore e84_ports; // create(port_id), get(port_id), ...
Convenience pass-throughs: E84PortStore::on_signal_change auto-creates
the port on first use (ergonomic for demos); applications should call
create() explicitly with their full port set.
The two existing callsites (test_gem300_scenario, test_e87_wire_scenarios)
are updated. The multi-LP test now demonstrates the actual win:
interleaved LP1 load + LP2 unload handshakes that reach their
respective Ready states without sequencing, and an ES on LP1 that
does NOT affect LP2 — exactly the failure mode the previous design
couldn't catch.
Five new dedicated tests in test_e84_ports.cpp for the store itself.
COMPLIANCE.md §4i updated: row now reflects per-port design.

Four new test cases:
* S3F19 verify with matching map → SlotMapVerifyAck::Accept and
CSMS lands in Read on the equipment side.
* S3F19 verify with disagreeing map → Mismatch ack and CSMS lands
in Mismatched.
* 4 LPs + 4 carriers, host verifies CAR-1 (mismatch) and CAR-3
(match) — only those two carriers move on the CSMS axis;
CAR-2/CAR-4 stay NotRead. Confirms per-carrier independence.
* Multi-LP E84 handshake sequencing (load then unload) round-trips
through Idle. Documents that the current E84StateMachine is
per-equipment, not per-port — a future per-port FSM would
update this test alongside.
Closes#11 in the test-gap backlog.
