chore: migrate repo from pnpm to bun

[alexgorbatchev]

Summary

• switch the monorepo workspace manager from pnpm to Bun
• replace pnpm-based CI, release, and Vercel install/build commands with Bun equivalents
• remove pnpm workspace/lock/config files and add bun.lock
• update repo docs and internal skills to use Bun commands

Validation

• bun install
• bun run typecheck
• bun run build
• bun run build:agentation
• bun run --filter ./packages/example build
• bun run build:storybook
• bun run test
• bun run dev smoke check

Notes

• npm publish --provenance remains unchanged; this PR only replaces pnpm usage
• kept public install docs that mention pnpm/yarn/npm/bun for package consumers
