Pull request overview

This PR modernizes git-prune-branches by raising the minimum Node.js version, upgrading dependencies/tooling (TypeScript, lint/format), and tightening CLI + Git-branch handling with improved tests and CI coverage.

Changes:

• Raise runtime/tooling baseline (Node.js >= 22, ES2024 target, updated deps, TS 7) and refresh CI/publish workflows.
• Migrate from ESLint/Prettier to oxlint/oxfmt and add Vitest coverage thresholds + coverage in CI.
• Refactor CLI initialization to parse/validate args up front, configure the singleton store explicitly, and harden branch-name handling (-- + shell quoting).
