z.coerce.boolean() calls Boolean(value), so the string "false" is true. So are
"0", "no" and "off". Every feature flag set to false was silently on.
Caught by reading a startup warning that should not have been there: the
deployment logged "PRIME_SYNC_ENABLED is on but PRIME_API_KEY is unset" while
the .env plainly said false. Had the key been present, PIG would have started
polling a third-party API nobody asked it to poll.
Replaced with an explicit parser accepting 1/true/yes/on, treating an empty or
absent value as the default. Demonstrated both behaviours side by side before
committing.
