+# Build and run altimate-code locally from a compiled binary.
+#
+# Usage:
+#   ./script/local.sh              # build + run
+#   ./script/local.sh --skip-build # run without rebuilding
+#   ./script/local.sh -- --help    # pass flags to altimate-code
+#
+# The script:
+#   1. Builds a single-platform binary (current OS/arch) via `bun run script/build.ts --single --skip-install`
+#   2. Sets NODE_PATH so the compiled Bun binary can find @altimateai/altimate-core
+#   3. Launches the binary with any trailing arguments
