feat: migrate contentstack-cli-content-type v2 into cli-plugins monorepo

[cs-raj]

Summary

Migrates the contentstack-cli-content-type standalone plugin into the cli-plugins pnpm monorepo at packages/contentstack-content-type. This is the v2-beta line of the plugin (version 2.0.0-beta.0), following the same pattern established by apps-cli and tsgen migrations.

The npm package name is unchanged (contentstack-cli-content-type). All 6 commands (content-type:list, details, audit, compare, compare-remote, diagram) and their flags are identical to the standalone version.

Key decisions

• Jest retained — the source plugin uses Jest + ts-jest with 80% global coverage thresholds. Unlike most other packages in this monorepo (Mocha + Chai), Jest is kept to avoid rewriting 16 test files. The CI step uses npm run test:unit consistent with monorepo convention.
• Version 2.0.0-beta.0 — marks the first release from the monorepo on the v2-beta line; v1.x releases continue from v1-dev / main.

---

Test plan

• pnpm --filter contentstack-cli-content-type run build completes without errors
• pnpm --filter contentstack-cli-content-type run test — all 16 test files pass
• pnpm --filter contentstack-cli-content-type run test:coverage — 80% global thresholds met
• pnpm --filter contentstack-cli-content-type run lint — ESLint clean
• NODE_ENV=PREPACK_MODE pnpm -r --sort run build (full monorepo build) passes
• csdx plugins:link inside packages/contentstack-content-type then csdx content-type:list -a <alias> returns content types
• Existing packages unaffected — no regressions in monorepo unit-test workflow
