Agentic QA Onboard — First-time tour of this repo

Activate when a user lands on this repo for the first time and asks "where do I start?", "how does QA work here?", or invokes /agentic-qa-onboard. The skill is a guided tour, not an executor: it explains the stack, the QA pipeline (pre-sprint Stage 0 + in-sprint Stages 1-6), the MCPs, and the env vars that everything depends on, then hands off to the right downstream skill.

This skill is specific to this Playwright + KATA QA boilerplate and points at the concrete entry points (/shift-left-testing, /sprint-testing, /test-automation, /test-documentation, /regression-testing, /framework-development).
