ci: skip duplicate CI runs and remove client from Supabase prestart (#497)

# Add CI optimization to skip duplicate runs

This PR adds a new pre-job step to our CI workflow that skips duplicate runs when the tree content has already passed CI. This is particularly useful for Graphite rebases with no code changes.

The implementation uses the `fkirc/skip-duplicate-actions@v5` action to detect duplicate runs, and all subsequent jobs now depend on this pre-job check with a condition to skip if the pre-job indicates the run is a duplicate.

Additionally, the PR removes "client" from the Supabase pre-start script parameters in the build-and-test job.
