bug: DependsOnConflictAnalyzer only reports first dependency cycle

[thomhurst]

Description

File: TUnit.Analyzers/DependsOnConflictAnalyzer.cs (Lines 121-142)

The method returns immediately when it detects the first cycle in the dependency graph:

if (chain.MethodTraversed(foundDependency))
{
    chain.Add(foundDependency);
    return chain;  // Returns immediately — misses other cycles
}

If a dependency graph has multiple cycles, only the first one is reported. Users must fix one cycle, rebuild, and discover the next one iteratively.

Suggested Fix

Continue processing all dependencies and accumulate all cycles before returning, so all cycles are reported at once.
