Rewrite Gemini chunk and link parsing logicv0.3.0
Improved the chunk-finding regex and added safeguards to prevent
unintended behavior.
Chunk rendering logic had a bug. If the pre-formatted text was identical
to the regular text, it would be wrongly overwritten. To resolve this,
the find-and-replace-style logic was removed. The new logic splits
chunks into parts, renders them, then reassembles them in in order.
