0xYYBB | ZYY | Bobo 724366a894 fix(prompts): correct confidence scale from 0-1 to 0-100 to match backend schema (#564) ...

## Problem

The prompts specified confidence range as 0-1 (float), but the backend code
expects 0-100 (integer). This causes JSON parsing errors when AI outputs
values like 0.85:

```
Error: json: cannot unmarshal number 0.85 into Go struct field Decision.confidence of type int
Result: confidence defaults to 0
```

## Root Cause

**Backend Definition** (decision/engine.go:103):
```go
Confidence int `json:"confidence,omitempty"` // 信心度 (0-100)
```

**Prompts (before fix)**:
- adaptive.txt: "confidence (信心度 0-1)"
- nof1.txt: "confidence (float, 0-1)"

**buildHardSystemPrompt** (decision/engine.go:336):
```go
sb.WriteString("- `confidence`: 0-100（开仓建议≥75）\n")
```

The dynamic system prompt was correct, but the base prompts contradicted it.

## Solution

Update prompt files to use consistent 0-100 integer scale:

### adaptive.txt
- `confidence (信心度 0-1)` → `confidence (信心度 0-100)`
- `<0.85` → `<85`
- `0.85-0.90` → `85-90`
- etc.

### nof1.txt
- `confidence (float, 0-1)` → `confidence (int, 0-100)`
- `0.0-0.3` → `0-30`
- `0.3-0.6` → `30-60`
- etc.

## Impact

- ✅ Fixes JSON parsing errors when AI outputs float values
- ✅ Aligns prompts with backend schema
- ✅ Consistent with buildHardSystemPrompt() output format
- ✅ No breaking changes (backend already expects 0-100)

## Testing

```bash
# Verify backend expects 0-100
grep "Confidence int" decision/engine.go
# Output: Confidence int `json:"confidence,omitempty"` // 信心度 (0-100)

# Verify buildHardSystemPrompt uses 0-100
grep "confidence.*0-100" decision/engine.go
# Output: sb.WriteString("- `confidence`: 0-100（开仓建议≥75）\n")

# Build test
go build ./decision/...  # ✅ PASS
```

- Addresses schema mismatch mentioned in Issue #557
- Note: confidence field is currently not validated by backend (validateDecision
  does not check confidence value), but correct schema prevents parsing errors
