parseBoolFalseDefault returned false only for explicit falsy literals
(including the empty string) and true otherwise, but the ComposeEnabled
call site negated it. The double error cancelled for an unset variable
(empty -> false -> !false -> true) but inverted every explicit value:
WORKER_COMPOSE_ENABLED=true disabled the subsystem while =false enabled
it. Rename the helper to parseBoolTrueDefault, drop the empty string
from the falsy set so unset stays on, and drop the negation. Add a
table-driven regression test pinning unset/true/1/yes -> on and
false/0/no/off (any case, trimmed) -> off.
- reconnect safely after token rotation and retry leased results
- reject malformed tasks and remove production cluster debug mutation
- validate environment files and require immutable container images
BREAKING CHANGE: Docker install, deploy, and Compose now require an
immutable repository@sha256 image reference.
