Eight tool modules (file_write, apply_patch, git_tool, db_query,
pdf_tool, image_tool, audio_tool, knowledge_tools) were missing from
openjarvis/tools/__init__.py. Their @ToolRegistry.register() decorators
never fired, so the /v1/tools endpoint never returned them and the
web UI agent wizard showed an incomplete tool list.
Add the missing imports and a regression test that checks all expected
tool names are in the registry after package import.
