Subject: [PATCH] fix(mcp): route _sqlite_graph_stats through sqlite_read_uri
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The graph_stats sqlite reader (#1837) and the sqlite_read_uri encoding fix
(#1838) landed in parallel, so _sqlite_graph_stats was the one reader left on
the naive f"file:{db_path}?mode=ro" construction that mis-parses paths with
spaces/special chars. Convert it too — now every read-only sqlite reader
percent-encodes its path. sqlite_read_uri is already imported in mcp_server
from #1838, so this is a call-site-only change.
