Fix Control renderer issues that UI5 linter reports but cannot auto-fix. Use this skill when linter outputs these rules: - \`no-deprecated-control-renderer-declaration\` - For missing renderer declaration, string-based renderer declaration, implicit renderer auto-discovery (removed in modern UI5) - \`no-deprecated-api\` - For missing apiVersion:2 in renderer objects, missing IconPool import when using oRm.icon(), deprecated rerender() override. NOTE: For Library.init() apiVersion errors, use fix-library-init instead. - \`ui5-class-declaration\` - For non-static renderer property in ES6 classes Trigger on: "missing a renderer declaration", "Deprecated declaration of renderer", "deprecated renderer", "apiVersion" (in renderer context), "IconPool", "rerender", "renderer must be a static property" Converts legacy renderer patterns to modern apiVersion: 2 format with proper module imports.

## From README

Fix Control Renderer Issues This skill fixes Control renderer issues that the UI5 linter detects but cannot auto-fix because they require understanding of the control's rendering behavior and module dependencies. Linter Rules Handled | Rule ID | Message Pattern | This Skill's Action | |---------|-----------------|---------------------| | no-deprecated-control-renderer-declaration | Control '...' is missing a renderer declaration | Add renderer: null or import renderer | | no-deprecated-control-renderer-declaration | Deprecated declaration of renderer '...' for control '...' | Import renderer module and assign directly | | no-deprecated-api | Use of deprecated renderer detected.
