0.7.5 Release

This releases extends the library's abilities while consolidating how it's meant to be used. It improves group mode functionalities, and add many optional filters to clean up the bot's output.

General Improvements

• Added option to remove starting slop like "Oh, X..." and "short narration" at the start of output
• Instruct Format: Added BotStartOverride and BotEndOverride to make instruct format compatible with GPT-OSS
• Instruct Format: Added added NoInstructInStopString flag to not put Bot and User Start/End tags in the stop strings
• Refactored TextPromptBuilder to use SingleMessage objects for structured message handling.
• Added ContainsPersona method to ChatSession for persona checks.
• More configurable handling of away message function (can be forced despite timing through parameter).
• Improved "roleplay" output filtering to remove slop content.
• Added option in brain to freeze mood in a given state (allows to still have mood inserts, but they won't change over time)
• Added ImageEmbedSize setting (defaults to 768). This is used for token usage tracking for VLM.
• Added SessionDetailedSummary setting to toggle between concise and detailed session summaries.
• Added ParenthesizeToItalic option to StringFix, converting (text) to text in output.
• Updated documentation

Group Chat Mode

• Better support for group chat personas and role alternation.
• Added GroupChatPastSessionMode setting to control secondary personas' access to main persona's chat history
• Introduced GroupInstructFormatAdapter setting to enforce user/bot role alternation for group conversations independently of who sent the message.
• Group persona now import ExampleDialogs fields from current bot, and Scenario from primary bot.
• Secondary character have only access to messages from sessions they were a part of. This should help with continuity.
• New method to allow CoT models to work with group chat and "Add name to prompt" setting in general. Who is supposed to talk is inserted as a prefill in the CoT instead.
• Added CommitGroupSessionToSecondaryPersonaHistory setting to allow group chat sessions to be saved to secondary personas' histories.

Fixes

• Fixed issue with CoT prefill in chat completion mode.
• Fixed issue in forced alternate role mode for group chat.
• Fixed Brain memory retrieval to not include memories with MemoryInsertion set to None.
