CLI v2: OAuth, JSON output, and automation-first overhaul

[nicped]

Summary

• OAuth client_credentials authentication — new --oauth login flow, --auth flag to override auth mode, env-var-based client credentials (--clientIdEnv/--clientSecretEnv)
• Structured JSON output — --output json across all commands with consistent response envelope (ok, status, data, errors, meta), replacing the deprecated --json flag
• File operations — --delete, --copy, --move support with --asFile/--asDirectory overrides and interactive confirmation for destructive actions
• Code quality — output.finish() via finally blocks, extracted isFilePath helper, encapsulated meta access in output objects, verbose logging for archive cleanup errors, fixed missing output parameter threading through setupEnv/interactiveEnv/interactiveOAuthLogin
• Documentation — full v2 documentation article, changelog, updated README

QA test scripts

To run the unit tests:

npm test

For QA to run the test smoke harness against a real solution:

export DW_BASE_URL=https://your-solution.example.com
export DW_CLIENT_ID=your-client-id
export DW_CLIENT_SECRET=your-client-secret
npm run qa:smoke

Full instructions (profile format, CI usage, --mode flag, etc.) are in qa/README.md.
https://github.com/dynamicweb/CLI/blob/7ce694f8464dd53c659f26d1950d6fc947b8aebd/qa/README.md

Test plan

• Run dw with no args — verify environment status display, including when env is missing
• Run dw login --oauth — verify interactive OAuth setup stores config correctly
• Run dw query <name> --output json — verify clean JSON output with no console noise
• Run dw files --delete <path> — verify confirmation prompt and correct API call
• Run dw files --copy <src> --output json — verify JSON envelope
• Run dw files --export <path> -v — verify verbose log shows correct operation context
• Verify --output json and --interactive conflict on the query command
• Verify deprecated --json flag on files command emits warning and still works

Pull request overview

This PR introduces a v2/beta overhaul of the DynamicWeb CLI focused on automation-first usage: OAuth client-credentials authentication, consistent --output json envelopes across API-driven commands, expanded file operations (delete/copy/move), and updated documentation/changelog to reflect the new behaviors.

Changes:

• Add OAuth client-credentials support (--auth oauth, dw login --oauth, env-var based client ID/secret) and surface auth type in the base dw command.
• Add structured JSON output (--output json, deprecated --json) to env, login, files, query, and command.
• Expand dw files with destructive/mutating operations (--delete, --empty, --copy, --move) and update docs/README/changelog for v2.
