fix: test start-screen for --dry-run mode for solve and hive commands (issue #539)

[konard]

Summary

Fixes #539

Problem

start-screen hive "https://github.com/konard" --dry-run --once --verbose was failing with "Invalid GitHub URL: missing owner/repo" because start-screen.mjs was not using the same URL validation logic as the hive and solve commands.

Root Cause

The original start-screen.mjs had its own URL validation that required both owner and repo, rejecting valid user/organization URLs like https://github.com/konard.

Fix

• src/start-screen.mjs: Updated to import and use the shared parseGitHubUrl from github.lib.mjs, ensuring consistent validation across all commands
• tests/test-start-screen.mjs: Added comprehensive --dry-run tests for both solve and hive commands
• .github/workflows/release.yml: Added CI step to run tests/test-start-screen.mjs (Issue We need to make sure we test start-screen for --dry-run mode for both solve and hive commands #539)

Accepted URL types

• ✅ User URLs: https://github.com/owner
• ✅ Repository URLs: https://github.com/owner/repo
• ✅ Issue URLs: https://github.com/owner/repo/issues/123
• ✅ Pull Request URLs: https://github.com/owner/repo/pull/456

Tests

All tests pass locally:

Testing --dry-run mode for solve command...
  solve --dry-run: ✓ PASSED

Testing --dry-run mode for hive command with user URL...
  hive --dry-run user URL: ✓ PASSED

Testing --dry-run mode for hive command with repo URL...

✅ Ready to merge

All requirements for issue #539 are satisfied:

• Fix: src/start-screen.mjs uses the shared parseGitHubUrl from github.lib.mjs, accepting user/org URLs like https://github.com/konard (consistent with hive and solve commands)
• Tests: tests/test-start-screen.mjs includes --dry-run tests for both solve and hive commands (including the exact failing case from the issue)
• CI: .github/workflows/release.yml runs test-start-screen.mjs as a check step

All CI checks pass. PR has no merge conflicts.
