Method refresh_file_token_map

src/mcp/server.rs:1173–1181

Re-read the file-to-token-count map from the DB and swap it into the cached `file_token_map`. Called after each lazy sync triggered by [`maybe_sync_if_stale`](Self::maybe_sync_if_stale) so the accounting tracks newly indexed / removed files.

        // best-effort; leave stale map in place if the DB read fails

            return;
        };
