Fix issue bug: lz:deploy requires deploy task name matches contractName

[farivar-tabatabaei]

This pull request improves the user experience when deploying contracts with specific tags in the Hardhat deployment task. Now, if a user specifies tags but no contracts are deployed (and there are no errors), the tool will warn the user accordingly. The test expectations have been updated to reflect this new behavior.

Deployment task improvements:

• Added a check in deploy.ts to warn the user if tags are specified but no deploy scripts match, and set a non-zero exit code in this case.

Test updates:

• Updated the test expectation file deploy-all-missing-tag.exp to expect the new warning message when no deploy scripts match the specified tag.

Fixes #1066

PR Summary

Improves feedback for tagged deployments that result in no changes.

• In deploy.ts, after aggregating results, computes totalDeployedContracts and, if selectedTags are provided with zero deployments and no errors, logs a warning (No contracts were deployed), sets process.exitCode, and returns early
• Updates deploy-all-missing-tag.exp to expect the new warning instead of the success message
