Revert "Update sqlcheck/execution.py: refine execution retry logic"

[Copilot]

Reverts commit c1e4a22 which added sqlcheck/execution.py.

Changes

• Removed sqlcheck/execution.py file containing duplicate run_test_case and run_cases functions
• These functions already exist in sqlcheck/runner.py with identical logic (aside from parameter naming: adapter vs connector)

The execution module was unused - no imports or dependencies existed elsewhere in the codebase.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• astral.sh
  • Triggering command: /usr/bin/curl curl -LsSf REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
