Pull request overview

This PR introduces a new DevExtreme licensing mechanism, adding a devextreme-license CLI and bundler plugin support to inject a generated license key into DevExtreme’s internal config during builds. It also adds a new LCP (product-only) key validation path and updates license warning/reporting behavior.

Changes:

• Add devextreme-license CLI + supporting Node-side license key discovery/conversion utilities (LCX → LCP).
• Add an unplugin-based bundler plugin to replace a license-key placeholder in m_config at build time.
• Add LCP key parsing/validation logic (product-kind bit flags, expiration checks) and update license warnings/tests.

fail() exits with status code 0 even for fatal CLI errors (unknown args, refusing to overwrite existing output file, etc.). This makes scripts/CI treat failures as success and can leave a stale or missing license key output unnoticed. Please exit with a non-zero code (e.g., 1) for error conditions, and keep 0 only for successful runs.

--cwd parsing will consume the next argument even if it's another flag (e.g., --cwd --force results in cwd='--force'). Consider mirroring the --out handling: validate that a path argument exists and doesn’t start with -, otherwise warn or fail.
