Add Root/Jailbreak Detection Coverage for Newer Bypass Techniques

[maugauwi-hash]

Area: Security Hardening
Priority: Medium
Estimated Time: 2.5 hours

Description:
#118 added basic jailbreak/root heuristics (IntegrityChecker.kt / IntegrityService.swift).
Root-hiding modules (Magisk Hide/Zygisk, Shadowsocks-style hook frameworks) and jailbreak tweaks
that patch common detection checks (file-existence, su binary checks) evolve faster than a static
heuristic list, so this should be revisited periodically rather than treated as done.

Tasks:

• Review current detection heuristics in IntegrityChecker.kt/IntegrityService.swift against
  known modern bypass techniques
• Add supplementary signals (e.g., unexpected writable system paths, suspicious installed packages)
  where feasible without excessive false positives
• Add a changelog/versioning note so this list has an owner for future revisits
• Add tests for any new heuristics added

I’d like to pick up issue #272 to expand root and jailbreak detection coverage across Android and iOS. I have solid experience with mobile security hardening, anti-tampering heuristics, and client integrity checks in Kotlin and Swift.

Implementation plan:

Heuristic Audit & Supplementary Signals: Review IntegrityChecker.kt and IntegrityService.swift against modern bypass mechanisms (e.g., Zygisk/Magisk Hide, hook frameworks). Add targeted supplementary signals such as unexpected writable system paths and suspicious package signatures while guarding against false positives.

Versioning & Ownership: Add an internal versioning note and changelog to the integrity services to maintain ownership and enable periodic heuristic reviews.

Testing & Verification: Add unit test coverage for new detection heuristics across mock Android and iOS environment states.

Ready to jump on this right away and submit a clean PR!
