What
When the SendFile (file-delivery) tool receives a path that looks like a URL (https://..., ftp://..., etc.), it now returns an actionable error message instead of silently failing or producing a confusing "file not found" error.
Details
- New error text:
"looks like a URL, not a local file path. This tool can only send files that exist on the local filesystem — download or write the content to a local file first, then pass that path." - The tool description is also updated to clarify: "Files must already exist on the local filesystem — the tool sends files, it doesn't fetch URLs or render content."

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
