fix: replace pnpm/action-setup@v6 with corepack in all CI workflows

All CI workflows updated to use corepack instead of pnpm/action-setup@v6:
- ci.yml (4 jobs)
- lint.yml
- release.yml
- changeset-release.yml
- performance-budget.yml
- shadcn-check.yml
- storybook-deploy.yml
- storybook-tests.yml
- dependabot-auto-merge.yml

Corepack reads the exact packageManager field from package.json with SHA verification, ensuring consistent pnpm version across local dev and CI.
