Task 3.0: Verify Pre-commit Hook Failure Behavior

Test File Created

Created test-spell-check.md with intentional spelling errors to verify the cspell hook failure behavior.

Test File Content

# Test Spell Check

This is a test file to verify that the cspell hook correctly identifies spelling errors.

## Intentional Errors

Here are some intentional spelling errors:
- "teh" instead of "the"
- "receive" instead of "receive" (intentionally misspelled as "recieve")
- "separate" instead of "separate" (intentionally misspelled as "seperate")

These errors should be caught by the cspell hook when attempting to commit this file.

Commit Failure Verification

When attempting to commit the file with spelling errors, the commit fails with clear error messages:

git add test-spell-check.md
git commit -m "test: verify cspell hook failure behavior"

Output:

cspell...................................................................Failed - hook id: cspell - exit code: 1 1/1 test-spell-check.md 589.79ms X test-spell-check.md:9:4 - Unknown word (recieve) fix: (receive) test-spell-check.md:10:4 - Unknown word (seperate) fix: (separate) CSpell: Files checked: 1, Issues found: 2 in 1 file.
