Security vulnerabilities and automated fixes for zip extraction issues

The `adm-zip` dependency resolved to 0.6.0 in this project's dependency tree, a version affected by CVE-2026-102282: during extraction it applies the Unix permission bits stored in each ZIP entry's external file attributes verbatim, including the setuid (`04000`), setgid (`02000`), and sticky bits. An attacker who controls an archive passed to `extractAllTo()` or `extractEntryTo()` can therefore have the extractor create a setuid binary owned by whatever user the extraction process runs as. The
A critical heap buffer overflow vulnerability was discovered in `TKLiveSync/unzip.cpp`, where ZIP archive entry names were copied into a `PATH_MAX`-sized heap buffer using `strcpy()` without any length validation. Since the ZIP specification allows entry names up to 65,535 bytes — far exceeding typical `PATH_MAX` values of 1,024 to 4,096 bytes — a crafted archive could overflow the buffer and corrupt heap memory. The fix replaces the unsafe `strcpy`/`dirname` pattern with `std::string` operation
