fix(reader): construct QSet with explicit insert loop for Qt5/Qt6 com…

[GongHeng2017]

…patibility

The iterator-range constructor QSet(begin, end) was introduced in Qt 5.14, causing a build failure on Qt 5.11.3. Using QSet::fromList() instead would break Qt6 builds since it was removed in Qt6. Replace with an explicit insert loop, which compiles on all supported Qt versions (5.11.3, 5.14+, and 6.x).

Log: 修复QSet构造方式在Qt5.11.3和Qt6上的编译兼容性问题
Bug: 本地编译时发现的问题，并无 bug 链接
Influence: 解决reader模块在Qt5.11.3下编译报错，同时保持Qt6兼容

Reviewer's Guide

Updates restored-file set construction in the reader to avoid the QSet iterator-range constructor unavailable in Qt 5.11.3, while retaining compatibility with Qt 6 and existing file merge behavior.

File-Level Changes

Change	Details	Files
Replace the Qt version-sensitive range construction of the restored-file set with an explicit, cross-version insertion loop.	Initialize an empty QSet and insert each restored path individually. Preserve duplicate filtering and restored tab ordering behavior while supporting Qt 5.11.3, Qt 5.14+, and Qt 6.x.	reader/main.cpp
