koko210Serve e1f81e52e5 Fix Miku confusing who said what in conversations
Three interrelated fixes for speaker attribution confusion:

1. Fix misleading episodic memory header (discord_bridge.py):
   The Cat core hardcodes '## Context of things the Human said in the past:'
   when formatting recalled conversations. Our plugins store BOTH user messages
   ([User]: prefix) AND Miku's own responses ([Miku]: prefix) in episodic memory.
   This misleading header primes the LLM to attribute Miku's words to the user.
   Replaced with '## Past conversation excerpts (prefixed by who said what):'
   which accurately describes the mixed-speaker content.

2. Tighten episodic recall (discord_bridge.py):
   Added before_cat_recalls_episodic_memories hook setting threshold=0.75
   (vs default 0.7) to reduce the chance of Miku's own just-uttered response
   being recalled on the very next user message, which would feed her own
   words back as misleading context.

3. Add role clarification (miku_personality.py & evil_miku_personality.py):
   Added a clarifying note after '# Conversation until now:' in the prompt
   suffix to explicitly tell the model that 'Human = the user, AI = you (Miku)',
   helping it reconcile the two labeling systems (episodic [User]/[Miku] prefixes
   vs conversation history Human/AI roles).
