gsxdsm 97e6a0cc0e fix(FN-5256): skip cycle preflight when new task has no deps

The unconditional listTasks() in assertNoDependencyCycle was wasted work
for the common no-dependency write and broke the same-agent duplicate
intake fail-open path: tests that stub listTasks to throw had the cycle
check consume the rejection before _maybeAutoArchiveSameAgentDuplicate's
try/catch could swallow it, propagating the error out of createTask.

patch

Skip the dependency-cycle preflight in TaskStore.assertNoDependencyCycle when the new task or update has no dependencies. The FN-5256 cycle-check rollout (e12adeb3f) added an unconditional listTasks() call on every write to build the dependency lookup, but an empty dependency list can never form a cycle so the query was wasted work. It also broke fail-open semantics in the same-agent duplicate intake path: tests that stubbed listTasks to throw saw the cycle check consume the rejection and propagate "boom" out of createTask before the duplicate-intake try/catch could swallow it.
