xiaoen b84adacc2f fix(routing): address review feedback on CJK estimation and observability
1. CJK token estimation: replace flat rune_count/3 with script-aware
   counting — CJK runes (U+2E80–U+9FFF, U+F900–U+FAFF, U+AC00–U+D7AF)
   count as 1 token each, non-CJK runes at /4. This fixes a 3x
   underestimate for Chinese/Japanese/Korean text that could incorrectly
   route complex CJK messages to the light model.

2. Routing observability: SelectModel now returns the computed score as
   a third value. selectCandidates logs the score on both paths — Info
   level for light model selection, Debug level for primary model
   selection.

3. Added tests: TestExtractFeatures_TokenEstimate_Mixed (CJK+ASCII mix),
   TestRouter_SelectModel_ReturnsScore.

Addresses review feedback from @mingmxren.
