chore: repo cleanup for v0.2.0

- Fix read_cpu_temp loop: ok()? was aborting iteration on unreadable hwmon
  entries instead of continuing to the next; use let Ok(...) else continue
- Fix osd.rs: replace stdout.unwrap() with defensive let-else guard
- PKGBUILD: bump pkgver to 0.2.0, replace libpulse dep with wireplumber +
  pipewire-pulse + brightnessctl (actual runtime tools used)
- bakery.toml: same dep fix as PKGBUILD
- Cargo.toml: fix repository URL casing (breadway -> Breadway)
- theme.rs: add wifi-popover-row-unsaved opacity rule
