Add override to the Lit controller hooks.

BaseController declares these hooks as abstract members. The Lit controller subclasses implement them without override, so TypeScript 6.0.3 reports TS4114 when compiling lit-query. This affects the current compile and test:types paths, which test:pr includes through its affected targets.

Suggested fix 
-  protected onConnected(): void {
+  protected override onConnected(): void {
-  protected onDisconnected(): void {
+  protected override onDisconnected(): void {
-  protected onHostUpdate(): void {
+  protected override onHostUpdate(): void {
-  protected onQueryClientChanged(): void {
+  protected override onQueryClientChanged(): void {

Apply these modifier changes to the same four hooks in the Lit controller subclasses under packages/lit-query/src/, and in packages/lit-query/src/__tests__/BaseController.test.ts.

Review comment at @tsconfig.json at line 22:
Add the override modifier to the onConnected, onDisconnected, onHostUpdate, and
onQueryClientChanged implementations in the Lit controller subclasses and
BaseController tests, marking each implementation as overriding its abstract
BaseController member.
