Add a /test skill to run singular tests or per module tests (#5111)

* Add a /test skill to run singular tests or per module tests

* fix(test): Correct Android task detection in test skill

Map modules ending in -android to testDebugUnitTest so Android library
modules like sentry-launchdarkly-android do not fall back to test.

Add AskUserQuestion to allowed-tools so interactive mode can execute the
decision prompts described in the skill under restricted tool settings.
