Fixes the gap that Phase 1b step 4 surfaced: the legacy pinNetMap was
built from board endpoints only, so the bridge from legacy solver to
MixedModeScheduler had nothing to publish for component pins like
"q1:C" — every SpiceResolvedPinResolver was stuck on FLOATING.
Now pinNetMap contains an entry for every wire endpoint, board or
component. Backwards compatible: legacy ADC injection only ever looked
up `boardId:pinName` keys, which are unchanged.
The new e2e integration test wires up real ngspice (eecircuit-engine,
no mock):
Arduino pin 9 → 1k → 2N2222 base; collector via 220 to 5V
- pin 9 HIGH → BJT saturated → Vc ≈ 0.05V → resolver emits LOW
- pin 9 LOW → BJT cut off → Vc ≈ 5V → resolver emits HIGH
Validated against the AVR_HC logic family (Phase 3). With 216 tests
green across 25 files, the Phase 1b pipeline is now demonstrably
correct end-to-end against a real SPICE solver, not just mocks.
