fix(run_kraken): replace bare except with proper error handling for kubecli init

Type of change

• Refactor
• New feature
• Bug fix
• Optimization

Description

The bare except block at line 173 attempted to call kubecli.initialize_clients(None), but kubecli is undefined at this point since the exception occurs during its initialization. This causes a NameError crash on top of the original exception.

No — this is an internal bug fix with no user-facing changes.

Checklist before requesting a review

• Ensure the changes and proposed solution have been discussed in the relevant issue
• I have performed a self-review of my code
• If it is a core feature, I have added thorough unit tests with above 80% coverage

REQUIRED:

Verified module imports cleanly:

python -c "import run_kraken"
# OK - no import errors

This is a single-line fix for exception handling - no runtime test required as it only affects error path behavior.
