Pull request overview

This PR modernizes the project's tooling infrastructure by migrating from Yarn to PNPM, replacing Jest with Vitest for testing, and switching from TSC to tsdown for bundling. The changes also unify CI/CD workflows, pin Node.js and PNPM versions, remove pre-push hooks, and include semantic-release as a direct dependency.

Changes:

• Replaced package manager from Yarn to PNPM with pinned version and workspace configuration
• Migrated test framework from Jest to Vitest with unified configuration for unit and integration tests
• Replaced TypeScript compiler with tsdown bundler for building, targeting Node 24 and CommonJS output
• Unified CI/CD workflows into a single workflow file with separate CI and CD jobs
• Updated dependencies and modernized import syntax to use type-only imports where appropriate
