tvOS: allow diagnostic bundled game data

[joeblack2k]

Summary

• prefer the normal tvOS cache location for GMSE01 data
• fall back to BundledGameData/GMSE01 only when the cache is absent
• keep production behavior unchanged when no diagnostic data is bundled

Validation

• python3 -m unittest tests.test_tvos_contract
• Release build for Woonkamer Apple TV succeeded
• locally injected GMSE01 bundle passed tvOS data validation and reached the Extended Gamepad gate on physical Woonkamer hardware

No game data is included in this PR.

Physical Woonkamer validation: a locally injected, re-signed BundledGameData/GMSE01 folder passed the existing header/main.dol checks, loaded gGMSE01_recomp.dylib, and rendered the Sunshine intro. No game data is tracked or attached to this PR.

Thank you for investigating a faster diagnostic path. I’m not incorporating the bundled-data fallback because it crosses a hard release boundary: SunPad’s public app/IPA may contain the runtime and generated executable module, but never retail extracted game data. Allowing BundledGameData/GMSE01 at runtime would make an accidental private-data bundle appear valid and weaken the cache-only staging contract. The reviewed integration in #42 instead used this finding to harden both app and package audits so BundledGameData is explicitly rejected. The supported diagnostic path remains validated staging into Library/Caches/SunPad/GameData/GMSE01. I’m closing this PR without merging.
