Strategy/Scala: refactor detectDependencyPlugins to find-based lookup

Replace the nested if-then-else with a `find` over a precedence-ordered
lookup table. Behavior is identical: `find` returns the first match so
ModernDependencyTreePlugin still wins over Legacy, and the shared
": enabled in" suffix keeps the three effective marker strings unchanged.
