ZhouYongyou bf782526e7 fix(decision): replace fullwidth space (U+3000) in JSON ...

Critical bug: AI can output fullwidth space (　U+3000) between brackets:
Input:  ［　｛"symbol":"BTCUSDT"｝］
        ↑ ↑ fullwidth space

After previous fix:
        [　{"symbol":"BTCUSDT"}]
         ↑ fullwidth space remained!

Result: validateJSONFormat failed because:
- Checks "[{" (no space) ❌
- Checks "[ {" (halfwidth space U+0020) ❌
- AI output "[　{" (fullwidth space U+3000) ❌

Solution: Replace fullwidth space → halfwidth space
- 　(U+3000) → space (U+0020)

This allows existing validation logic to work:
strings.HasPrefix(trimmed, "[ {") now matches ✅

Why fullwidth space?
- Common in CJK text editing
- AI trained on mixed CJK content
- Invisible to naked eye but breaks JSON parsing

Test case:
Input:  ［　｛"symbol":"BTCUSDT"｝］
Output: [ {"symbol":"BTCUSDT"}]
Validation: ✅ PASS
