fix: Evil Miku wordiness regression from username prompt changes

Five targeted fixes:

1. discord_bridge (priority 100): Skip 'cheerful virtual idol' wrapper and
   'CRITICAL INSTRUCTION' about facts when evil_mode is active. Evil Miku
   gets her own prompt from evil_miku_personality plugin.

2. memory_consolidation (priority 10): Soften fact-usage pressure:
   'Use THESE facts when answering' → 'You may reference these facts if
   relevant to the conversation'. Also soften username command tone.

3. evil_miku_personality (priority 100→101): Bump above discord_bridge
   so Evil Miku's prefix replacement deterministically discards any
   Miku-mode wrappers regardless of plugin load order.

4. evil preamble: Restructure for brevity — add 'Be SHORT and SHARP'
   declaration, move RESPONSE RULES before mood, tighten sentence limit
   from 2-4 to 1-3 with 'if you can say it in one, say it in one.'

5. evil suffix: Add final brevity reminder '[Keep responses short and
   cutting — 1-3 sentences. No monologues.]' right before conversation
   for maximum recency influence.

 RESPONSE RULES:
-- 2-4 sentences typically. Short enough to sting, long enough to land.
+- 1-3 sentences. If you can say it in one, say it in one.
 - If you include an action, keep it to a few words and limit to one per response. Most responses need no actions at all.
 - Don't monologue or narrate scenes — you're talking, not writing.
 - Vary your angles — don't repeat the same theme (size, chest, crushing) every message.
