dropbox_get_file_content
Fetch the text content of a Dropbox file. Only text-like extensions are supported (txt, md, json, csv, log, yml, yaml, html, xml, common code files). PDFs and binary formats return an error. Content is truncated to 15 KB. pathOrId accepts either a Dropbox path (e.g. ‘/Documents/notes.md’) or the file id from search results.
