fix: 修复所有 Clippy 警告，CI 质量门禁全部通过

- agent.rs: !...is_some() → .is_none() (nonminimal_bool)
- config.rs: 去掉 macOS/Windows 块多余 return (needless_return)
- config.rs: &old_pkg → old_pkg (needless_borrow)
- logs.rs: 第二处 saturating_sub + filter_map → map_while (lines_filter_map_ok)
- memory.rs: 两处 for/if-let → .iter().flatten() (manual_flatten)
- tray.rs: let _ = future → std::mem::drop (let_underscore_future)
