fix(gateway): classify Windows SVG MIME alias as active content (#5594)
* fix(gateway): classify Windows SVG MIME alias as active content

Treat Windows' image/svg alias like the standard image/svg+xml active content type.

* test(gateway): cover Windows SVG MIME alias

Pin image/svg classification independently of the host MIME database.

* docs(utils): document platform MIME aliases

Record the shared active-content classification invariant.

Message Text Extraction

message_content_to_text takes raw message content and treats None as empty text so downstream empty-result, error-detail, and archive-skip fallbacks work. Keep its other conversions unchanged, including newline-separated list blocks and literal strings such as "None". Do not replace it with message_to_text, which takes a whole message and uses different list/mapping semantics. Regression coverage lives in tests/test_utils_messages.py, tests/test_subagent_executor.py, and tests/test_task_continuity.py.

Agent / Tool Assembly Off-Load

Tool and agent assembly re-enters get_available_tools() and may block on MCP discovery, so the four async assembly entry points — run_agent's agent_factory call, task_tool, durable batch _execute_item, and abuild_checkpoint_state_accessor — dispatch through deerflow.utils.assembly_io.run_assembly, a dedicated ContextVar-preserving bounded executor (DEER_FLOW_ASSEMBLY_WORKERS, default 8) rather than the loop's default executor; a hung MCP server therefore parks an assembly worker instead of queueing unrelated default-executor work, and the pool logs a warning when pending assemblies exceed the worker count. tests/blocking_io/test_tool_assembly_offloop.py pins all four offloads plus the ContextVar propagation.

Uploaded Document Summaries

file_outline.py reads outlines and fallback previews as utf-8-sig so an optional leading UTF-8 BOM cannot hide a first-line heading or code fence, or occupy a preview line. Preserve physical line numbers, embedded U+FEFF characters, and the original file bytes.

Active Content MIME Types

text_detection.py::_is_active_content_mime_type is the shared download-safety boundary for artifacts and project documents. Keep platform aliases such as Windows' image/svg aligned with their standard active type (image/svg+xml), and preserve the generic +xml rule.
