Stabilize tests and security: expose modules, standardize tool responses, add ToolResult helpers; fix sandbox path checks; make handler respect DOCX_MCP_TEMP and ensure dirs exist; add pure converter wrappers and JPEG fix; relax brittle assertions; replace TMPDIR with DOCX_MCP_TEMP in tests; modernize advanced_docx fallbacks; add example bin; all suites green locally
