Subject: [PATCH] fix(44): skip dimmed source nodes in getConnectedInputs

When paths reconverge downstream of a Switch, dimmed nodes (from disabled
outputs) still held stale data from previous runs. getConnectedInputs now
accepts dimmedNodeIds and skips any source node in the dimmed set, preventing
disabled Switch paths from leaking data into downstream nodes.
