fix(decision): handle fullwidth JSON characters from AI responses

Browse Source

## Problem
AI occasionally outputs fullwidth (全角) characters in JSON responses,
causing JSON parsing failures even though content is logically correct.

Example error:
  JSON format validation failed: actual [ {"symbol": "BTCU...
  (displays as fullwidth: ［｛"symbol"："BTCU...)

## Root Cause
Claude API can output fullwidth characters when:
- Processing Chinese context
- Mixing languages in responses
- Input method artifacts

## Current Protection
Already handles curly quotes but not brackets/punctuation

## Solution
Extend fixMissingQuotes() to handle fullwidth JSON syntax:
- Brackets: ［］ -> []
- Braces: ｛｝ -> {}
- Colon: ： -> :
- Comma: ， -> ,

## Impact
- Prevents intermittent JSON parsing failures
- No performance impact (simple string replace)
- Does not affect correctly formatted responses
