Improve model card: Add pipeline tag, library name, paper/GitHub links, and abstract

This PR enhances the model card by:
- Adding `pipeline_tag: text-generation` to ensure better discoverability for users searching for models related to text generation tasks (e.g., at https://huggingface.co/models?pipeline_tag=text-generation).
- Adding `library_name: transformers` as the model's `config.json` and `tokenizer_config.json` indicate compatibility with the Hugging Face Transformers library (`Qwen2ForCausalLM`, `Qwen2Tokenizer`), enabling the "Use in Transformers" widget and code snippets.
- Including the paper abstract for a more comprehensive overview of the model's capabilities directly on the Hub.
- Adding the paper link ([AceSearcher: Bootstrapping Reasoning and Search for LLMs via Reinforced Self-Play](https://huggingface.co/papers/2509.24193)) and the GitHub repository link ([https://github.com/ritaranx/AceSearcher/](https://github.com/ritaranx/AceSearcher/)) for quick access to the research and code.
- Including a "Training" section based on the GitHub README.
- Ensuring the existing "Model Usage" code snippets are preserved exactly as found in the original README, without introducing new example variables or imports, as per guidelines.

Please review and merge this PR if everything looks good.

+# AceSearcher: Bootstrapping Reasoning and Search for LLMs via Reinforced Self-Play
+
+## Abstract
+Search-augmented LLMs often struggle with complex reasoning tasks due to ineffective multi-hop retrieval and limited reasoning ability. We propose AceSearcher, a cooperative self-play framework that trains a single large language model (LLM) to alternate between two roles: a decomposer that breaks down complex queries and a solver that integrates retrieved contexts for answer generation. AceSearcher couples supervised fine-tuning on a diverse mixture of search, reasoning, and decomposition tasks with reinforcement fine-tuning optimized for final answer accuracy, eliminating the need for intermediate annotations. Extensive experiments on three reasoning-intensive tasks across 10 datasets show that AceSearcher outperforms state-of-the-art baselines, achieving an average exact match improvement of 7.6%. Remarkably, on document-level finance reasoning tasks, AceSearcher-32B matches the performance of the DeepSeek-V3 model using less than 5% of its parameters. Even at smaller scales (1.5B and 8B), AceSearcher often surpasses existing search-augmented LLMs with up to 9x more parameters, highlighting its exceptional efficiency and effectiveness in tackling complex reasoning tasks. Our code will be published at this https URL and this https URL .
