DynamicDataPinManager is responsible for keeping the set of DynamicDataPins on a NodeBranch in sync with its NodeConditionRef list. Whenever the node's conditions change (preset added, removed, or updated), the manager regenerates the pin set to match.

Design constraints:

• Pin UUIDs are stable between calls to SyncPins() as long as the condition-index and operand-side are the same. This allows the host to persist pin IDs across saves.
• O(1) pin lookup by UUID via an internal std::map.
• Color coding: dynamic data pins are yellow (ImVec4(1,1,0,1)).
• Labels use the format: "In #<N><L|R>: <condPreview>" e.g. "In #3L: [Pin:1] <= [Pin:2]"

Usage:

DynamicDataPinManager mgr(registry);
mgr.SyncPins(node.conditions);          // regenerate / keep existing
node.dynamicPins = mgr.GetAllPins();    // write back to node
 
// When a preset is deleted:
mgr.InvalidatePreset(deletedPresetID);
node.dynamicPins = mgr.GetAllPins();

C++14 compliant — no std::optional, structured bindings, std::filesystem.
