fix: reject trailing newline in tool-name and URI-template varname validation ( #3076 )
...
Python's $ with re.match also matches just before a single trailing newline, so tool-name validation accepted "name\n" and UriTemplate.parse accepted varnames like "foo\n". Switch both checks to re.fullmatch.
