v0.1.8 — fix Gaming Mode 60 Hz launch on NVIDIA + HDMI

Browse Source 
Reported by clutchmuffin: TUI saved e.g. CUSTOM_REFRESH_RATES=165 but
Gaming Mode always launched at 60 Hz. Two stacked bugs:

1. Settings TUI wrote ~/.config/environment.d/gamescope-session-plus.conf
   but never reloaded systemd's user env, so the running user manager
   (and therefore gamescope-session-plus@.service) still had the old
   values until next login. Now flush_pending calls
   `systemctl --user import-environment` / `unset-environment` for the
   keys it just touched.

2. CUSTOM_REFRESH_RATES was written as a single scalar. Gamescope's
   --custom-refresh-rates is a list of *switchable* rates, not a
   launch-rate selector — and with no safe 60 Hz fallback in the list,
   some DRM/NVIDIA paths drop to the EDID-preferred 60 Hz on first
   launch. TUI now writes a comma list (e.g. 60,165). show_state and
   confirm_risky_save de-list to the highest member for display /
   validation.

Adds a troubleshooting README entry documenting the Steam BPM
client-side rate persistence as the canonical first-launch workaround.
