feat: migrate @contentstack/cli-cm-regex-validate to cli-plugins monorepo (v2-beta)

[cs-raj]

Summary

Migrates @contentstack/cli-cm-regex-validate from its standalone GitHub repository into the cli-plugins pnpm monorepo as packages/contentstack-cli-cm-regex-validate, targeting the v2-beta CLI dependency line.

⚠️ First npm release — this package has never been published to npm. Version 2.0.0-beta.0 is set intentionally as the initial beta release.

What's included

• Package source — full migration of src/, test/, bin/, messages/, config files
• package.json — version 2.0.0-beta.0, v2 deps (@contentstack/cli-command ~2.0.0-beta.7, @contentstack/cli-utilities ~2.0.0-beta.8), oclif upgraded ^3.17.2 → ^4.23.0, jest moved from dependencies → devDependencies, monorepo repository/homepage/bugs, scripts: build, test:unit, lint, clean, prepack: pnpm run build
• tsconfig.json — added composite: true, esModuleInterop: true
• jest.config.ts — fixed testMatch to include test/ directory (source had tests/ only, breaking test discovery)
• Release workflow — added publish step to release-v2-beta-plugins.yml with tag: beta
• CI — added test step to unit-test.yml
• release.json — added "regex-validate": false
• Docs — REGEX-VALIDATE-MIGRATION.md at monorepo root, root AGENTS.md updated with Regex Validate section
