[Awesome-Ace22]

What and why

Adds a "Where to work" note to CONTRIBUTING.md. It tells contributors to clone this repo into the dev/ folder of a Nova-Collected clone (e.g. Nova/dev/frontend) and branch from dev, and never to work in the prod/ or pi/ submodules, which are overwritten on release. Also repoints the testing-procedure reference from the old docs/testing-procedure.md path to its current location in Nova-Collected (docs/development/testing-procedure.md).

How was this tested?

Docs only, so no level applies. I read the rendered CONTRIBUTING.md and checked that the new testing-procedure link points at the file's current path in Nova-Collected.

Hardware impact

• None - UI, docs or tooling only
• Changes how a sensor is read, converted or shown
• Changes how an actuator is commanded, or safety rules, interlocks, timeouts or sequencing → add the hardware-risk label; a lead must approve
• Changes a message format, MQTT topic or FAS protocol that another repo depends on → title needs !, link the matching PRs:

Checklist

• Targets dev (or main for a release/hotfix, or with a reason given above)
• Branch is up to date ("Update branch" button)
• No station config/calibrations, data files, secrets, .env files or build output committed
• README/docs updated if behaviour changed (this PR is the docs update)
