koko210Serve a226bc41df Rewrite is_miku_addressed() to only trigger when addressed, not mentioned ...

- Pre-compile 393 name variants into 4 regex patterns at module load
  (was 7,300+ raw re.search() calls per message)
- Strict addressing detection using punctuation context:
  START:  name at beginning + punctuation (Miku, ... / みく！...)
  END:    comma + name at end (..., Miku / ...、ミク)
  MIDDLE: commas on both sides - vocative (..., Miku, ...)
  ALONE:  name is the entire message (Miku! / ミクちゃん)
- Rejects mere mentions: 'I like Miku' / 'Miku is cool' no longer trigger
- Script-family-aware pattern generation (Latin, Cyrillic, Japanese)
  eliminates nonsensical cross-script combos (e.g. o-みく)
- Word boundary enforcement prevents substring matches (mikumiku)
- Fixes regex 'unbalanced parenthesis' errors from old implementation
- Add comprehensive test suite (94 cases, all passing)
