chore: fix lint debt blocking pre-push

- claude-code-config.ts: merge concatenated strings into one template literal
  (useTemplate) and wrap long conditional per formatter.
- declare-tweak-schema.test.ts: replace non-null assertions with optional
  chains (noNonNullAssertion).

All changes are biome check --fix --unsafe output. No behavior change.
