Use isWatchOnce flag in watch branch

PeterDaveHello · PeterDaveHello · commit 7d79fc744d3b · 2025-09-02T02:38:55.000+08:00
Prefer the precomputed isWatchOnce flag over re-reading the environment
variable to keep logic consistent and easier to reason about. No behavior
change; retains existing watch-once exit handling.
