• Replaces generic Docker URL with Windows-specific link in WSL messages.
• Adds platform-specific Docker installation URLs (Windows, Mac, Linux) in client_state initialization.
• Refactors message printing to use a shared url variable and updates NOTICE link assignments.

• The notification in show_wsl_messages now mentions Docker instead of WSL, which may confuse users. If the intent is to guide WSL setup, restore the WSL-specific messaging or move this Docker instruction to a more appropriate location.

            "Some BOINC projects require Docker.  <a href=%s>Learn how to install it</a>",

client/client_state.cpp:947

• The string concatenation is invalid and will not compile. Consider using proper escaping and std::string concatenation, for example:

n.description = std::string("Some projects require Docker. ... <a href=\"") + url + "\">here</a>";

        n.description = "Some projects require Docker.  We recommend that you install it.  Instructions are <a href=" + (string)url + (string)">here</a>.";

[nitpick] These platform-specific URLs are repeated; consider centralizing them in a constant map or helper function to reduce duplication and ease future updates.
