fix(audits): apply browser-runtime rules to @sim/utils; align settings checklist with the standalone description rule

[waleedlatif1]

Summary

• check:utils skipped packages/utils/src and the allowlisted files for every pattern, so toSorted/toReversed/toSpliced, useRef(new X()), and h-N w-N went unchecked in @sim/utils, which ships to the browser
• The exemption now covers only the 13 rules that ban re-implementing a helper (replacesHelper: true); every other rule, including any added later, applies everywhere by default
• sim-settings-pages.md checklist step 1 required unified.description, contradicting the paragraph above it that allows planes.<plane>.description for a standalone-only section; step 1 now defers to that paragraph

Type of Change

• Bug fix

Testing

• Probed: toSorted in a packages/utils/src file is flagged; an inline helper primitive there still passes
• bun run lint, bun run type-check, bun run check:audits (58), docs-manifest:check, block-registry check, root bun run test (all suites)

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing (new tests pass the test-audit authoring gate)
• No new warnings introduced
• I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)

[Medium risk] Updates code-style rules and adds enforcement tests.

The PR appears safe to merge; no outstanding or newly introduced actionable issue was identified.

Summary

The PR narrows helper-source exemptions so browser-runtime rules also scan @sim/utils and allowlisted files, adds regression tests, and makes the settings checklist consistent with its description guidance.
