From 5e3180a334df03baee7ff1f24d3bae2494dd0c69 Mon Sep 17 00:00:00 2001 From: Ralph Bean Date: Mon, 20 Apr 2026 15:07:13 -0400 Subject: [PATCH 1/6] feat: add --vendor-fullsend-binary flag for dev iteration When passed to `fullsend admin install`, cross-compiles the fullsend binary for linux/amd64 and uploads it to .fullsend/bin/fullsend. The GitHub Action checks for a vendored binary before downloading from releases, enabling rapid iteration without cutting a release.
