- extract_images: only remove extracted image tags from content, preserve
non-image markdown links (e.g. PDFs) that were previously silently lost
- truncate_message: walk only chunk_body (not prepended prefix) so the
reopened code fence does not toggle in_code off, leaving continuation
chunks with unclosed code blocks
- Add 49 unit tests covering MessageEvent command parsing, extract_images,
extract_media, truncate_message code block handling, and _get_human_delay
- Sanitize filenames in cache_document_from_bytes to prevent path traversal (strip directory components, null bytes, resolve check)
- Reject documents with None file_size instead of silently allowing download
- Cap text file injection at 100 KB to prevent oversized prompt payloads
- Sanitize display_name in run.py context notes to block prompt injection via filenames
- Add 35 unit tests covering document cache utilities and Telegram document handling
