Allow Hercules to read chats from other apps

User scenario: When simultaneously developing two or more related software products (e.g. a backend app and a client app), developers currently have to manually switch between multiple Hercules chats and copy-paste questions and answers back and forth. This is very inconvenient.

Requested capability: Allow two or more chats (across different Hercules apps) to exchange messages or share context — so that a question asked in one chat can be answered using knowledge from another chat, without manual copy-pasting. Possible implementations could include: linked chats, shared context snippets, or a cross-app reference feature.

We are actually piloting this. Should be available in the next 7 days.
