LLM-generated tool calls may wrap URLs in markdown backticks or quotes
(e.g. \https://example.com\), causing urlparse to produce empty scheme
and netloc, which leads to all fetch attempts failing silently.
Add URL cleaning at the top of WebFetchTool.execute to strip whitespace,
backticks, double quotes, and single quotes, plus an early rejection guard
for non-http(s) URLs after cleaning.
The Enabled column in channels status and plugins list commands had a default green style that overrode the dim markup for disabled items. This caused no values to appear green instead of dimmed. Remove the default style to let cell-level markup control the display correctly.
