Fix #2804

This PR fixes a false positive in the spelling check where -latest was incorrectly recognized as atest.

Root Cause:
The compiler flags pattern in .github/actions/spelling/patterns.txt included a lowercase l in the character class [DPWXYLlf]. When encountering -latest, the pattern would match -l, leaving atest to be flagged as a misspelling.

Solution:
Removed the lowercase l from the pattern, changing -[DPWXYLlf] to -[DPWXYLf]. This change:

• Prevents false positives with words like -latest
• Still matches legitimate compiler flags (-D, -P, -W, -X, -Y, -L, -f)
• The uppercase L remains for library path flags like -L/path/to/lib

Files Changed:

• .github/actions/spelling/patterns.txt (line 53)

Test

To test this pull request, you can run the following commands:

• The spelling check will run automatically when this PR is created
• To verify manually, create a test file with:

echo "version: -latest" > test-spelling.txt
echo "flag: -latest-tag" >> test-spelling.txt

Before the fix: -latest would match -l, leaving 'atest' as false positive
After the fix: -latest is not matched by the pattern, so 'latest' is checked as a whole word (valid)Verification:

• Created test file with -latest to verify the fix
• Confirmed the pattern change is syntactically correct
• Verified that legitimate compiler flags still match correctly
