Description
This Pull Request updates the verification scripts (verify.sh) across 14 exercise folders to improve their reliability, fix logic
errors, and ensure they correctly validate the student's work.

Key Changes:

1. Robust Existence Checks: Standardized the way the scripts check for resources (e.g., Namespaces). Changed 2>/dev/null to

   /dev/null 2>&1 to ensure that kubectl output doesn't leak into the shell variables, preventing false positives/negatives during
   boolean evaluation.

2. Exercise 08 (Probes) Fix: Corrected a hardcoded pod name mismatch where the script was looking for probe-pod instead of the
   required probe-test.
3. Exercise 13 (Init Containers) Fix:
   • Added whitespace trimming (tr -d ' ') to wc -w counts. Some environments return leading/trailing spaces with wc, which caused
     integer comparisons to fail.
   • Added || true to pipe chains to prevent the script from exiting prematurely if a command in the middle of a check returns a
     non-zero exit code.
4. Consistent Exit Handling: Improved the shell logic to ensure that "Verifying..." headers and "━━━━━━━━" separators are displayed
   correctly even if specific tasks fail.

Affected Folders:
The verify.sh file was updated in the following directories:

• exercises/01-pod-basics through exercises/14-in-place-scaling

Verification Results:
Tested the scripts locally to ensure they now accurately report a "Pass" when the solution is correct and provide a clear "Fail" when
the resource is missing or incorrectly configured.
