Extending IntelliJ-based IDEs at runtime
summary
Runtime extension of IntelliJ-based IDEs using LivePlugin and Kotlin compiles a plugin.kts into classes loaded by a fresh classloader per evaluation, with a disposable lifecycle so unload works. Examples include registering actions and action groups via registerAction, editing editor text with executeCommand + write actions and undo, running shell tasks and HTTP requests (http4k) with addToClassPath, reordering menus by finding action IDs, and adding folding/inspections by adapting the Kotlin folding builder; reloadable state and PSI tooling remain rough.
