The evaluate-and-suggest half of M6: a read-only findings report (D9) over
system settings that affect gaming stability/performance, each with the exact
fix command.
- core/gameenv.py: PCIe ASPM, NVIDIA persistence mode, CPU governor (the three
seed-case contributors to GPU bus-drop / Xid 79), GameMode, MangoHud,
vm.swappiness, shader disk cache, THP, CPU mitigations, Proton versions.
Pure evaluate_* helpers split from IO for testing; reuses the M4 Finding model.
- steam.proton_versions(): surfaces installed Proton builds for the report.
- CLI: rigdoctor gameenv (text / --json); render_health() gained a title arg.
- GUI: new Environment page; extracted a shared finding_card widget and switched
the Health page to it.
- Tests for the pure evaluators + aggregate.
Also fix: desktop notifications now use the RigDoctor icon (installed theme copy
-> bundled asset -> stock fallback) instead of a generic stock icon, matching
the app/dock icon.
Docs (MODULES/ROADMAP) updated; version 0.8.0 -> 0.9.0.
