chore(deps-dev): bump @vitest/eslint-plugin to 1.3.20 (supersedes #7701)

[jherr]

Standalone replacement for #7701, applied directly on top of main.

Why not just merge #7701

#7701 (renovate/vitest-eslint-plugin-1.x) was branched against an older tree pinned to vitest 3.2.4 and conflicts with main. Merging it would downgrade vitest. This PR applies only its intent — the @vitest/eslint-plugin 1.3.13 → 1.3.20 bump — with no other version changes.

Changes

• @vitest/eslint-plugin → 1.3.20. Its @typescript-eslint ^8.46.1 dependency resolves as a nested subtree, so the top-level typescript-eslint stays at 8.45.0 and vitest stays at 3.2.4.
• 1.3.20 enables the prefer-called-exactly-once-with rule; the 5 flagged assertions across 3 test files are collapsed into toHaveBeenCalledExactlyOnceWith(...) (eslint --fix + prettier).

No .npmrc / legacy-peer-deps needed — this is purely on vitest 3.

Verification

Local (Node 24): lint, typecheck, format:check pass; 373/373 unit tests pass. Integration/e2e not run locally (need auth token / network / Git LFS).

Closes #7701.

Walkthrough

The @vitest/eslint-plugin development dependency in package.json is bumped from 1.3.13 to 1.3.20. Three test files are updated to comply with the updated plugin: generate-autocompletion.test.ts, registry.test.ts, and config-github.test.ts each replace separate toHaveBeenCalledOnce() plus toHaveBeenCalledWith(...) assertion pairs with a single toHaveBeenCalledExactlyOnceWith(...) call at four assertion sites total.
