feat(orchestrator): auto node interview after inclusion (part of #203)

[Assar63]

The core of #203 — the post-inclusion interview now runs automatically, closing the gap where device identity was only gathered on a manual poke.

What

src/orchestrator/InterviewOrchestrator.cpp (bus-only, priority 204): on a node joining it runs an ordered Get sequence, advancing on each matching typed report:

ManufacturerSpecific -> Version -> [Multi Channel endpoints if CC 0x60] -> [Z-Wave+ Info if CC 0x5E] -> NodeInterviewComplete

• The ManufacturerSpecificReport it triggers feeds PolicyRegister::noteDeviceIdentity, so device-level policy defaults become matchable (the headline gap from the issue).
• Ordering: realises SecurityBootstrap → Interview — a node whose NIF advertises S0/S2 is deferred until it reports secure (NodeSecurityStatus), so the Gets ride the encrypted channel; a non-secure node is interviewed straight off NodeIncluded.
• Emits NodeInterviewComplete{nodeId} — the seam the InclusionOrchestrator policy step will key off (next layer).

Manifest adds the NodeInterviewComplete event and an orchestrator publisher on the four Get*Command events.

Tests

3 bus-driven tests: rich node runs the full 4-step sequence to completion; a minimal node skips the optional endpoint/Z-Wave+ steps; a secure node defers until NodeSecurityStatus. 474/474 ctest green on both gnu and llvm; clang-format + clang-tidy clean.

Remaining #203 layers

• gate the InclusionOrchestrator policy step on NodeInterviewComplete (order becomes SecurityBootstrap → Interview → Policy, device defaults match);
• persist the gathered identity (mfr/product, CC versions, endpoints, Z-Wave+ role) into node-registry so the console detail pane + Node info window #45 show it;
• sleeping-node interview via PendingQueue.

Part of #203. Hardware acceptance under #189.
