# Builds standalone PodTui binaries for each supported OS/arch and attaches
# them to a GitHub Release. One runner per platform because Bun cannot
# cross-compile — each runner runs `make dist`, which emits a
# podtui-<platform>-<arch>.tar.gz (binary + native libs side by side).
#
# Trigger: push a tag like v0.1.0. Bump VERSION in src/index.tsx in the same
# commit as the tag so the released binary reports the tagged version.
