feat(compose): validate runServices against compose file services

[skevetter]

Summary

Adds upfront validation that each service listed in runServices actually exists in the referenced docker-compose file's services: map. Previously, typos in runServices would pass silently through config loading and only fail with confusing errors at container start time. Now a clear error is returned immediately, listing all invalid service names (e.g. runServices: service(s) not found in compose file: [typo-service]).

• Added validateRunServices() in pkg/devcontainer/compose.go called after LoadDockerComposeProject returns
• Unit tests covering: empty list, all valid, invalid only, mix of valid/invalid, empty project
• E2E test fixture with an invalid runServices entry asserting the error message

Warning

Rate limit exceeded

@skevetter has exceeded the limit for the number of commits that can be reviewed per hour. Please wait 37 minutes before requesting another review.

To keep reviews running without waiting, you can enable usage-based add-on for your organization. This allows additional reviews beyond the hourly cap. Account admins can enable it under billing.

After the wait time has elapsed, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

We recommend that you space out your commits to avoid hitting the rate limit.

🚦 How do rate limits work?

CodeRabbit enforces hourly rate limits for each developer per organization.

Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout.

Please see our FAQ for further information.
