`ExtensionCatalog.download_extension` and `PresetCatalog.download_pack` read `download_url` from catalog payload data and pass it to `urlparse(...).hostname` during the HTTPS validation. A malformed authority (e.g. an unterminated IPv6 bracket like `https://[::1`) makes urlparse/hostname raise a raw `ValueError`, which escapes past the command handlers — they only catch `ExtensionError` / `PresetError` — and surfaces as an uncaught traceback. Guard the parse in a try/except and re-raise as the domain error so the CLI reports a clean "download URL is malformed" message. Mirrors the same fix in catalogs (github#3435) and workflows/catalog.py (github#3484). Adds regression coverage for both catalogs. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
