fix(command-development): correct grep pattern in testing-strategies

[sjnims]

Summary

Fix incorrect grep pattern in troubleshooting documentation.

Problem

The grep command for verifying bash command syntax was searching for !\`` (escaped backtick) instead of !`` (the actual bash pre-execution syntax).

Solution

Changed grep '!\'togrep '!' to match the correct pattern.

Testing

• Markdownlint passes

PR Review: #62 - fix(command-development): correct grep pattern in testing-strategies

Summary

✅ Looks good - This is a straightforward documentation fix that corrects an incorrect grep pattern.

What Changed

The PR fixes line 680 in testing-strategies.md:

• Before: grep '!\'` (escaped backtick - incorrect)
• After: grep '!'` (correct pattern matching bash pre-execution syntax)

What's Good

• Correct fix: The change properly aligns with the bash pre-execution syntax documented in PR docs(command-development): document bash ! prefix for pre-execution syntax #55. The ! prefix (without escaping the backtick) is the correct pattern to search for.
• Context-aware: The fix is in the "Debugging Failed Tests" section under "Issue: Bash commands not executing", where users would verify they're using the correct `!`` syntax (testing-strategies.md:673-685)
• Minimal scope: Single-line change with no side effects
• Clean commit: Well-formatted commit message following conventional commits
• Markdown quality: Markdownlint passes with no issues

Technical Verification

The grep pattern fix is correct because:

1. The actual bash pre-execution syntax is `!`` (exclamation + backtick)
2. In a grep pattern with single quotes, backticks don't need escaping
3. The old pattern grep '!\'` would search for a literal backslash-backtick sequence (wrong)
4. The new pattern grep '!'` correctly searches for exclamation-backtick (right)

Checklist Verification

• ✅ File location correct: references/testing-strategies.md (skill reference documentation)
• ✅ Markdown linting passes
• ✅ Change aligns with plugin documentation standards
• ✅ Testing checklist completed (markdownlint confirmed in PR body)
• ✅ No breaking changes
• ✅ README/CLAUDE.md updates not needed (internal reference doc only)

Recommendation

Approve and merge - This fix improves the accuracy of the troubleshooting documentation and should be merged.
