pub const ALLOW_SKEW_ENV: &str = "BYNK_ALLOW_SKEW";Expand description
#1675: the override for the skew gate below. Every gated command honours
it; bynk test also takes it as --allow-skew. Any non-empty value allows
a skewed bynkc (the same “non-empty means set” contract as the CI
BYNK_REQUIRE_* switches).
