Copilot can the text say: Source (just the json/markdown content)

Updated the download UI text as requested. Changed "Source content (just the content)" to "Source (just the json/markdown content)" and the button text from "Source content" to "Source". This makes it clearer what type of content is being downloaded. (e5b4c4f)

Copilot i meant the mode text should be dynamic, not literally show both "json/markdown"

Updated the download text to be dynamic based on the current mode. Now it shows "Source (just the json content)" when in JSON mode and "Source (just the markdown content)" when in Markdown mode, instead of literally showing "json/markdown". (d4a8f4b)

Copilot can you make a displayMode variable that uses mode to make a safe displayable of it to avoid to fix the codeQL alerts

Copilot can you make a displayMode variable that uses mode to make a safe displayable of it to avoid to fix the codeQL alerts

Created a displayMode variable that safely maps the validated mode to display strings, which should fix the CodeQL alert. The variable ensures only pre-defined safe strings ('json' or 'markdown') are used in HTML construction instead of directly using user input. (90474ab)
