The `!darwin` guard on the modifier helpers was too broad: golang.design/x/ hotkey only exposes its Mod*/Key* constants from the darwin&&cgo, linux&&cgo and windows backends, while the `!windows && !cgo` complement (e.g. Linux cross-builds with CGO_ENABLED=0) falls back to a stub with no constants. That made hk.ModCtrl/ModShift/KeyA... undefined and produced editor/vet warnings. Realign the build tags with the upstream matrix and confine every hk.* constant to a tagged file so the shared hotkey.go compiles everywhere. Also fix the Linux mapping (option -> hk.Mod1; hk.ModAlt does not exist on X11).
