chore: upgrade to Go 1.26 and remove dead code for golangci-lint

Bump the go directive to 1.26.0 and switch the release workflow to
go-version-file so it tracks go.mod. Remove unused style vars and the
dead logo()/getPanelHelp() functions flagged by golangci-lint's unused
linter; golangci-lint now reports 0 issues.
