fix(catalog): reduce logging noise during parallel operations

Change catalog loading log message from INFO to DEBUG level to prevent
70+ "Loaded 68 catalog entries" messages during make update.

Each tool creates its own ToolCatalog instance, and with 70 tools running
in parallel, this created excessive logging noise. The summary message is
not critical for normal operations.
