Detailed Description

Migrates task graph JSON from schema v3 (BT-style) to schema v4 (VS-style).

Schema v3 uses a flat node list with NextOnSuccess / NextOnFailure integer fields to express control flow (Behavior-Tree-style).

Schema v4 replaces those fields with explicit ExecConnections and DataConnections arrays (Visual-Script-style), adds graphType, and bumps schema_version to 4.

Usage

std::vector<std::string> errors;
bool ok = TaskGraphMigrator_v3_to_v4::Migrate("input_v3.json",
                                               "output_v4.json",
                                               errors);
if (!ok) {
    for (auto& e : errors) std::cerr << e << "\n";
}

C++14 compliant - no C++17/20 features.
