Document processing

Supported extraction includes PDF, DOCX, TXT, Markdown, and PNG/JPEG/WEBP image inputs. Scanned documents can use Tesseract OCR. /extract-text performs size/signature checks in the web process and delegates decoding to a bounded child process; temporary work directories are removed and stale work is reconciled.

Relevant limits are configured with PARSER_TIMEOUT_SECONDS, PARSER_CPU_SECONDS, PARSER_MEMORY_MIB, and PARSER_STALE_WORK_SECONDS. PARSER_TEMP_ROOT is an optional local override. When a document exceeds safe limits, reject it or ask the user for a smaller/cleaner file; do not disable validation to make a parser pass.
