fix(tasks): inject outputFiles into Pebble context in CommandsWrapper.render() (#15758)

The run() method already built the outputFiles map for renderCommands(), but
render(RunContext, Property<String>) called from Script.run() used only
taskRunner.additionalVars() — no outputFiles — so {{ outputFiles.name }}
resolved at script render time with "Unable to find `outputFiles`".

Apply the same non-glob name→workingDir/name injection in render() so the
variable is available before run() is called.

Fixes #13765
