DX-5352 — Agent docs, skills, and dependency updates

Summary

Adds repository guidance for humans and AI tooling (AGENTS.md, skills/, .cursor/rules/), bumps Inquirer to v12 with matching import and test updates, refreshes TypeScript, ESLint, and Contentstack dependencies, and adjusts SCA / Talisman configuration. Minor style-only edits in validate-regex (semicolons / trailing commas).

Changes

Developer & agent documentation

• AGENTS.md — Project map, workflow (npm test, posttest), naming, pointers to @skills/* and .cursor/rules/.
• skills/ — Portable skills: testing (Jest patterns), contentstack-cli (command/SDK/schema/output), code-review (PR checklist); skills/README.md includes concrete @skills/... paths and CI Node 22.x (aligned with .github/workflows/unit-tests.yml).
• .cursor/rules/ — IDE rules (TypeScript, testing, oclif command, Contentstack utils, dev workflow) and README index.
• .cursor/skills/SKILL.md — Points authoritative packages at repo-root skills/.

Dependencies & tooling

• Inquirer 12.11.1 (pinned); default import in src/utils/interactive.ts; interactive.test.ts uses ESM-style imports and Promise.resolve mocks for inquirer.prompt (Inquirer v12 async behavior).
• TypeScript ^5.9.3, @types/node ^18, @typescript-eslint/* ^8.58, ts-jest / jest patch bumps; Contentstack CLI packages updated.
• Removed @types/inquirer (superseded by Inquirer v12 typings).
• .eslintrc — Explicit @typescript-eslint/parser and parserOptions.
• package.json version 1.3.1; package-lock.json regenerated.

CI / security

• .github/workflows/sca-scan.yml — Snyk step json: true, continue-on-error: true, and contentstack/sca-policy@main.
• .talismanrc — Restructured fileignoreconfig entries and checksums for current tracked files.
