+Stages (run in order):
+ tag Compute next version, create and push annotated tag
+ build Cross-compile for all release targets
+ pack Compress Linux binaries with UPX
+ upload Upload artifacts via release(1)
+
+Flags:
+ --from <stage> Start at this stage and continue through the rest
+ --only <stage> Run just this one stage
+ --help, -h Show this help
+
+With no flags, all stages run in order (tag → build → pack → upload).
+The tag stage also notifies the Go module proxy after pushing.
+
+Examples:
+ ./release.fish Full release
+ ./release.fish --from build Rebuild, pack, and upload (skip tagging)
+ ./release.fish --only build Just cross-compile
+ ./release.fish --only upload Re-upload existing dist/ artifacts"
