fix(sandbox): 对齐 Manus——读文件不默认硬截断 - #207

The file/read API defaulted to max_length=10000, which cut Computer panel file views, diffs, and agent file_read results with a "(truncated)" suffix. Worse, str_replace and find_in_content reused that truncated read, so replacing in files larger than 10KB could wipe the tail of the file. Default max_length to None (full content); keep optional truncation when callers pass an explicit limit. Always read the full file for replace/search. Co-authored-by: Simpleyyt <simpleyyt@gmail.com>
Restore the default 10k cap on file/read so agents cannot dump huge files into context, with a clearer truncation hint to use start_line/end_line. str_replace / find_in_content still read the full file to avoid corruption. Computer panel / file_view request max_length=null for untruncated display. Co-authored-by: Simpleyyt <simpleyyt@gmail.com>

Match official Manus: file/read has no default max_length; agents are guided to use start_line/end_line (start with first 20 lines when unsure). Context size is bounded by backend max_tool_result_chars (16k), not the sandbox API. Keep optional max_length for explicit caps; replace/search and UI still read full files.

file_read没有max_length，靠工具说明引导模型：start_line/end_line进模型的上下文体积由上层预算控制，而不是 sandbox API 硬砍。
