feat(libra): 为 log 命令添加 --oneline 参数，实现单行简洁格式显示提交历史 #1227

[zh66778]

此 PR 完成了 r2cn 测试任务 #1277，为 libra log 命令添加 --oneline 参数

功能描述
为 libra log 命令实现 --oneline 参数，显示简化的单行提交历史格式，兼容 git log --oneline 行为。

实现方案
在 LogArgs 结构体中添加 oneline 布尔字段，使用 clap 的 #[clap(long)] 注解
在 execute 函数中实现条件格式化逻辑：
oneline 格式：7位短哈希（黄色）+ 提交消息首行
保持原有详细格式不变
兼容现有 -n/--number 参数，可组合使用

测试覆盖
添加 test_log_oneline 测试用例
验证短哈希长度为7个字符
确保提交消息解析正确
测试与 --number 参数的组合使用

文档更新
更新 aria/contents/docs/libra/command/log/index.mdx
添加 --oneline 参数说明和功能描述

Pull Request Overview

This PR adds a new --oneline flag to the libra log command for displaying each commit on a single line with an abbreviated hash and the first line of its message.

• Introduces oneline boolean in LogArgs and implements conditional formatting in execute.
• Adds test_log_oneline to verify the one-line output logic.
• Updates documentation to describe the new --oneline option.

libra/tests/command/log_test.rs:131

• [nitpick] Consider capturing and asserting the full oneline-formatted output by invoking the execute function and capturing stdout. This end-to-end check will ensure the new flag’s behavior (including newline and formatting) is validated.

async fn test_log_oneline() {

libra/src/command/log.rs:93

• The oneline branch builds the output without a trailing newline. On Unix this causes entries to run together; consider adding a newline (e.g., use format!("{}\n", ...) or use writeln!) to ensure each commit is printed on its own line.

            format!("{} {}", short_hash.yellow(), msg)
