feat: Implement TRPG NER training and inference script with robust model path detection and enhanced timestamp/speaker handling

- Added main training and inference logic in main.py, including CoNLL parsing, tokenization, and model training.
- Introduced TRPGParser class for inference with entity aggregation and special handling for timestamps and speakers.
- Developed utility functions for converting word-level CoNLL to char-level and saving datasets in various formats.
- Added ONNX export functionality for the trained model.
- Created a comprehensive requirements.txt and updated pyproject.toml with necessary dependencies.
- Implemented tests for ONNX inference to validate model outputs.

+
+## 安装
+
+### 环境要求
+
+- Python >= 3.12
+- CUDA (可选，用于 GPU 加速)
+
+### 安装依赖
+
+```bash
+# 使用 uv (推荐)
+uv sync
+
+# 或使用 pip
+pip install -r requirements.txt
+```
+
+```
+
+```
+
+### 1. 数据准备
+
+将训练数据准备为 CoNLL 格式，支持两种格式：
+
+#### Char-level 格式 (推荐)
+
+```
+-DOCSTART- -X- O
+风 -X- _ B-speaker
+雨 -X- _ I-speaker
+  -X- _ O
+2 -X- _ B-timestamp
+0 -X- _ I-timestamp
+...
+```
+
+#### Word-level 格式
+
+```
+风雨 O O B-speaker
+2024-06-08 O O B-timestamp
+21:44:59 O O I-timestamp
+```
+
+### 2. 初次训练
+
+```bash
+# 基础训练（使用默认参数）
+uv run main.py --train --conll ./data
+
+# 完整参数训练
+uv run main.py --train \
+    --conll ./data \
+    --model hfl/minirbt-h256 \
+    --output ./models/trpg-final \
+    --epochs 20 \
+    --batch 4
+```
+
+#### 参数说明
+
+| 参数         | 说明                 | 默认值                   |
+| ------------ | -------------------- | ------------------------ |
+| `--train`  | 启用训练模式         | -                        |
+| `--conll`  | CoNLL 文件或目录路径 | `./data`               |
+| `--model`  | 基础模型名称         | `hfl/minirbt-h256`     |
+| `--output` | 模型输出目录         | `./models/trpg-ner-v1` |
+| `--epochs` | 训练轮数             | `20`                   |
+| `--batch`  | 批处理大小           | `4`                    |
+| `--resume` | 恢复检查点路径       | `None`                 |
+
+### 3. 推理测试
+
+```bash
+# 单文本测试
+uv run main.py --test "风雨 2024-06-08 21:44:59 剧烈的疼痛从头颅深处一波波地涌出..."
+
+# 多文本测试
+uv run main.py --test \
+    "莎莎 2024-06-08 21:46:26 \"呜哇...\" 下意识去拿法杖" \
+    "BOT 2024-06-08 21:50:03 莎莎 的出目是 D10+7=6+7=13"
+
+```
+
+#### 输出格式
+
+```json
+{
+  "metadata": {
+    "speaker": "风雨",
+    "timestamp": "2024-06-08 21:44:59"
+  },
+  "content": [
+    {
+      "type": "comment",
+      "content": "剧烈的疼痛从头颅深处一波波地涌出...",
+      "confidence": 0.952
+    }
+  ]
+}
+```
+
+## 增量训练
+
+在已有模型基础上继续训练新数据：
+
+```bash
+# 继续训练（自动加载最新检查点）
+uv run main.py --train \
+    --conll ./new_data \
+    --output ./models/trpg-final \
+    --epochs 5
+
+# 从指定检查点恢复
+uv run main.py --train \
+    --conll ./new_data \
+    --output ./models/trpg-final \
+    --resume ./models/trpg-final/checkpoint-200 \
+    --epochs 5
+```
+
+## 标签维度管理
+
+### 添加新标签训练
+
+在 CoNLL 数据中添加新的标签类型（如 `emotion`），模型会自动适配：
+
+```bash
+# 添加新标签后重新训练（使用 ignore_mismatched_sizes）
+uv run main.py --train \
+    --conll ./data_with_emotion \
+    --output ./models/trpg-final \
+    --epochs 15
+```
+
+### 减少标签维度训练
+
+如果需要减少标签类型，建议从头训练：
+
+```bash
+# 从基础模型重新训练（使用缩减后的标签集）
+uv run main.py --train \
+    --conll ./data_reduced_labels \
+    --model hfl/minirbt-h256 \
+    --output ./models/trpg-reduced \
+    --epochs 20
+```
+
+## ONNX 导出
+
+将训练好的模型导出为 ONNX 格式，用于 CPU 推理加速。
+
+> **注意**: ONNX 导出功能会自动使用推理时找到的模型目录。如果模型目录不在默认位置，请先���用 `--output` 指定正确的模型目录。
+
+```bash
+# 方式一：从默认模型目录导出（自动查找 models/trpg-final）
+uv run main.py --export_onnx \
+    --onnx_path ./models/trpg-final/model.onnx
+
+# 方式二：指定模型目录导出
+uv run main.py --export_onnx \
+    --output ./models/trpg-final \
+    --onnx_path ./models/trpg-final/model.onnx
+
+# 方式三：导出到其他路径
+uv run main.py --export_onnx \
+    --onnx_path ./models/trpg-optimized.onnx
+```
+
+### ONNX 模型特点
+
+- 支持 CPU 推理（无需 GPU）
+- 模型大小约 50-100 MB
+- 推理速度约 10-50 ms/句（取决于硬件）
+- 兼容 Windows/Linux/macOS/Raspberry Pi
+
+## ONNX 模型测试
+
+### 基础推理测试
+
+```bash
+# 使用 ONNX 模型进行推理
+uv run tests/onnx_infer.py "风雨 2024-06-08 21:44:59 剧烈的疼痛..."
+```
+
+#### 性能指标
+
+```
+Performance Results (n=100):
+   Average latency: 25.32 ms
+   P95 latency:     31.45 ms
+   Max RAM usage:   120.5 MB
+   Throughput:      39.5 sentences/sec
+```
+
+## 数据转换工具
+
+### CoNLL 转 Dataset
+
+```bash
+# 转换单个文件
+uv run src/utils/conll_to_dataset.py data.conll \
+    --output ./dataset/trpg \
+    --format jsonl \
+    --validate
+
+# 转换整个目录
+uv run src/utils/conll_to_dataset.py ./data \
+    --output ./dataset/trpg \
+    --format both \
+    --validate
+```
+
+#### 输出格式
+
+- `--format jsonl`: 输出 JSONL 格式
+- `--format dataset`: 输出 HuggingFace Dataset 格式
+- `--format both`: 同时输出两种格式
+
+### Word-level 转 Char-level CoNLL
+
+```bash
+uv run src/utils/word_conll_to_char_conll.py \
+    input_word.conll \
+    output_char.conll
+```
+
+## 高级功能
+
+### 自定义标签
+
+在 `src/webui/utils.py` 中修改 `DEFAULT_LABELS`：
+
+```python
+DEFAULT_LABELS = [
+    {"name": "timestamp", "color": "#87CEEB", "type": "text"},
+    {"name": "speaker", "color": "#90EE90", "type": "text"},
+    {"name": "dialogue", "color": "#FFB6C1", "type": "text"},
+    {"name": "action", "color": "#DDA0DD", "type": "text"},
+    {"name": "comment", "color": "#FFD700", "type": "text"},
+    # 添加新标签
+    {"name": "emotion", "color": "#FFA07A", "type": "text"},
+]
+```
+
+## 系统要求
+
+### 训练环境
+
+- CPU: Intel Core i5 或同等性能
+- RAM: 8 GB+
+- GPU: NVIDIA GPU（可选，用于加速）
+- 存储: 5 GB+
