fix(procfs): 修复进程名称显示问题 (#1245)

* fix(procfs): 修复进程名称显示问题

修改ProcessControlBlock::generate_name函数，使其只返回可执行文件的basename，
而不是完整的路径和所有参数。这样/proc/*/status中显示的进程名称将符合
Linux的行为规范。

例如：/bin/busybox 进程将显示为 "busybox" 而不是 "/bin/busybox -/bin/busybox sh --login"

* refactor(process): 简化进程名称生成逻辑

移除`generate_name`函数中未使用的`args`参数，简化代码逻辑。
