* feat: accept pdf, images and office files * refactor: rename FileConverter to FileParser, simplify file retain API - Rename engine/converters/ → engine/parsers/, FileConverter → FileParser, ConverterRegistry → FileParserRegistry, MarkitdownConverter → MarkitdownParser - Rename env var HINDSIGHT_API_FILE_CONVERTER → HINDSIGHT_API_FILE_PARSER - Remove async/document_tags params from FileRetainRequest (always async now) - Add retain_files() to Python Hindsight client and retainFiles() to TypeScript client - Add sample.pdf to doc examples for working file upload demonstrations - Update test_file_retain.py to use new parser names and always-async behavior - Fix Go client missing os import in api_files.go - Simplify postgresql.py storage to minimal schema * fix: update rust CLI tests to use is_supported_file instead of is_text_file * fix: patch Go api_files.go to add missing 'os' import after generation * fix: insert 'os' import after 'net/url' in api_files.go patch for correct position * chore: regenerate OpenAPI spec and clients (converter→parser description update)
