Handle Fiori Elements V2 controller extensions during UI5 modernization. Use this skill when: - Extension controllers use \`sap.ui.controller()\` AND the manifest has a matching \`controllerName\` entry (Case B → report only, do not modernize) - Extension controllers use \`Controller.extend()\` with manifest \`controllerName\` registration (Case B → report only, do not modernize) - Code contains \`registerControllerExtensions\` calls (Case A → ControllerExtension.extend + override) - Manifest.json has \`sap.ui5/extends/extensions/sap.ui.controllerExtensions\` with \`controllerName\` entries Case B (plain object) is by far the most common. For Case B, do NOT modify controller files — report them and move on. Case A requires actual code modernization. For plain controller definitions in custom (non-Fiori-Elements) apps where \`sap.ui.controller()\` is just defining a standalone controller, use \`fix-js-globals\` (Case 9) instead.

## From README

Fix Fiori Elements Controller Extensions This skill handles Fiori Elements V2 controller extensions during UI5 modernization. There are two cases with different actions: Case B (most common): Extensions registered via controllerName in manifest → Report only. Do NOT modify the controller files. Leave them as-is and inform the user which files need manual attention. Case A (rare): Extensions using registerControllerExtensions → Perform the full modernization to ControllerExtension.extend() + manifest registration.
