fix(build): strip \r\n from all .py files — CRLF breaks patch_ops.sh text matching

31 files had Windows line endings (\r\n) from merge commit. This causes
patch_ops.sh replace_once() to fail: anchor strings use \n but file
content has \r\n, so no match → patch fails → docker build fails.

Also added .gitattributes to force LF for all text files going forward.

+Patches vLLM 0.6.3 to register Qwen3CoderToolParser under the name "qwen3_coder".
+
 Deploy steps on the remote machine (already called by patch_ops.sh):
   1. patch_ops.sh locates vLLM with importlib.util.find_spec.
   2. cp qwen3coder_tool_parser.py into the detected vllm tool_parsers.
   2. python3 patch_vllm_tool_parser.py
