Biome 2 no longer includes style/noNonNullAssertion in recommended, so ! assertions slipped through. This turns the rule on as an error and replaces the 13 existing uses with narrowing.

• src: regex captures, the first array element, and Map.get are now checked, not asserted. enhance-and-categorize uses one flatMap in place of filter + map(c => c.scopes!).
• tests: createMockVersionOutput takes role / prerequisiteOf, so specs pass them in and don't set them afterwards through updates[0]!.

No behaviour change.

Summary

Enables Biome’s noNonNullAssertion rule and removes existing assertions.
