meta: retry image pulls in the database start scripts - #18340

Draft
Conversation
Docker Hub occasionally answers an image pull with "500 Internal Server Error", which fails the CI job within seconds of the start step beginning. Recent examples: mariadb oldest (Node 22) on #18327 and mysql oldest (Node 20) on #18337. Pull the compose project's images explicitly before `up -d`, retrying up to three times with a growing delay, so a transient registry error no longer fails the whole job.

Pull Request Checklist
yarn testoryarn test-DIALECTpass with this change (including linting)?Description Of Change
Docker Hub occasionally answers an image pull with
500 Internal Server Error, which fails the CI job within seconds of the start step beginning. Two recent examples:mariadb-oldest Error received unexpected HTTP status: 500 Internal Server ErrorHead "https://registry-1.docker.io/v2/library/mysql/manifests/8.0.19": received unexpected HTTP status: 500 Internal Server ErrorThis is not dialect-specific, so this PR covers every dialect's start script in one go rather than one PR per dialect.
Changes
dev/pull-images.sh: pulls a compose project's images, retrying up to 3 times (override withPULL_ATTEMPTS) with a 15s/30s delay between attempts.dev/*/{oldest,latest}/start.shcalls it beforedocker compose up -d, soupfinds the images already present.Verification
PULL_ATTEMPTS=2Note: this touches the same
start.shfiles as #18339 (oracle) and the db2 PR, so expect a trivial merge conflict in whichever lands last.🤖 Generated with Claude Code
