fix(cli): 在 zip 压缩阶段应用 --ignore-dirs 参数过滤指定目录

[sponge225]

Description

ov add-resource --ignore-dirs 参数此前仅被发送到服务端用于目录扫描阶段的过滤，但客户端 Rust CLI 在 zip 压缩打包阶段仍然将所有目录（包括 .git、node_modules 等）打包进 zip 文件，导致上传时可能超过 512MB 限制。

本次修改在客户端压缩阶段即通过 walkdir::filter_entry 剪枝忽略目录，从源头减小 zip 体积。

Type of Change

• Bug fix (non-breaking change that fixes an issue)
• New feature (non-breaking change that adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update
• Refactoring (no functional changes)
• Performance improvement
• Test update

Changes Made

• 新增 parse_ignore_dirs() 函数，解析逗号分隔的忽略模式字符串
• 新增 ignore_dirs_filter() 函数，生成 walkdir::filter_entry 闭包，支持 basename 匹配和相对路径匹配（含 / 的模式）
• 为 zip_directory 和 zip_directory_with_progress 增加 ignore_dirs: Option<&str> 参数
• 在三处 walkdir 遍历中应用 filter_entry 剪枝忽略目录
• 添加根目录保护，防止根目录名与忽略模式匹配时误剪枝整棵目录树
• add_skill 调用时传入 None，不影响 skill 添加流程
• 新增 12 个单元测试覆盖解析和过滤逻辑

Testing

• I have added tests that prove my fix is effective or that my feature works
• New and existing unit tests pass locally with my changes
• I have tested this on the following platforms:
  • Linux
  • macOS
  • Windows

验收结果：

• 测试目录含 .git 和 node_modules，原始大小约 32MB
• 使用 --ignore-dirs ".git,node_modules" 后，zip 体积缩减至 868B
• 不使用 --ignore-dirs 时，服务端兜底过滤仍生效（IGNORE_DIRS 默认列表）

测试过滤掉约一半的文件后，打包上传耗时约减少一半

Additional Notes

• 客户端过滤与服务端过滤互补：客户端在压缩阶段剪枝可减小上传体积，服务端在解析阶段过滤作为兜底
• 相对路径匹配语义与服务端 directory_scan.py 中的 _should_skip_directory 保持一致
