fix(local): make trial-build-patch.R detect non-throwing build failures
local/trial-build-patch.R -- the single-package acceptance gate the proposer tells humans to run -- reported "Trial build OK" for a build that actually failed (rstan's rstan.so failing to load with an undefined TBB symbol). Same root cause as the registry gate before #130: build_binary_package() catches failures internally and returns "error" rather than throwing, so a tryCatch that only treats a thrown exception as failure false-greens. Inspect the return value: a pass requires a non-empty result containing no "error" sentinel. Mirrors the fix in trial-build-registry.R.
