v0.9.2

Highlights

• Centralized Aleph, MCP, and sub-query env parsing behind typed pydantic-settings models while preserving Aleph's forgiving env coercion behavior.
• Consolidated document ingestion so mcp/local_server.py now uses mcp/io_utils.py as the single canonical loader path.
• Added optional markitdown-backed conversion for richer PDF/DOCX/HTML ingestion, plus PPTX/XLSX/XLS support when the docs extra is installed.
• Added optional OpenTelemetry spans around sub-query execution via aleph.observability.
• Added regression coverage for timeout env parsing and MarkItDown-backed document loading.
• Refreshed MCP install docs, development docs, and version metadata for 0.9.2.
