Fix CPU use bug

When I publish program level commands, they also come back around to my app causing it to
eat tons of CPU. Now I'm only publishing this when the state changes.

+## Some Pro Tips!
+
+- Use the `--on-focus-start` and `--on-focus-end` options to run commands that help you get into the zone and wind down after a focus period or to control your environment (e.g., turning off notifications).
+
+### My example usage
+
+I used Shortcuts on my mac to control macOS Focus mode. I named them "Turn On Focus" and "Turn Off Focus". This allows my focus start and end commands to control my notifications for my computer and phone (since I have them synced).
+
+I also use [Slack Status CLI](https://git.iamthefij.com/iamthefij/slack-status-cli) to set my Slack status to a snooze mode with a tomato emoji when I'm in focus mode and turn it off after.
+
+```sh
+gomodoro \
+    --fullscreen \
+    --color-left '#ecdfb1' \
+    --color-right '#c6e889 ' \
+    --on-focus-start "shortcuts run 'Turn On Focus'" \
+    --on-focus-start "say 'Time to focus'" \
+    --on-focus-start "slack-status -snooze -duration 1h -emoji :tomato: Focus" \
+    --on-focus-end "shortcuts run 'Turn Off Focus'" \
+    --on-focus-end "say 'Break time you slacker'" \
+    --on-focus-end "slack-status" \
+    --on-interval-end "say 'Interval done! Phew!'"
+```
