fix: Bash install script has CRLF line endings, fails on macOS/Linux

[willfalalikuo-hub]

⏺ ## Bug Description

install-safe-rm.sh 发布文件使用 CRLF (\r\n) 换行符，导致在 macOS/Linux 上执行失败：

/tmp/install-safe-rm.sh: line 10: : command not found
/tmp/install-safe-rm.sh: line 11: set: - invalid option
/tmp/install-safe-rm.sh: line 24: syntax error near unexpected token `{'

Steps to Reproduce

1. curl -sSL https://github.com/blueraincoatli/safe-rm-toolkit/releases/latest/download/install-safe-rm.sh -o install-safe-rm.sh
2. bash install-safe-rm.sh

Root Cause

发布文件使用 \r\n (CRLF) 而非 \n (LF)，通过 xxd 确认：

Workaround

tr -d '\r' < install-safe-rm.sh > install-safe-rm-fixed.sh
bash install-safe-rm-fixed.sh                                                                                                                                                                                                            
 
Suggested Fix                                                                                                                                                                                                                            
                                                          
1. 添加 .gitattributes 文件强制 shell 脚本使用 LF：                                                                                                                                                                                      
*.sh text eol=lf                                          
2. 或在发布前转换：sed -i 's/\r$//' install-safe-rm.sh                                                                                                                                                                                   
                                                                                                                                                                                                                                         
Additional Issue                                                                                                                                                                                                                         
                                                                                                                                                                                                                                         
macOS 的 trash 脚本中 osascript 语法有误，quoted form of 无法在 -e 单行模式中使用，应改为：                                                                                                                                              
                                                          
osascript -e "tell application \"Finder\" to delete (POSIX file \"$abs_path\")"
