Trac ticket: #65819

What

Adds a dedicated PHPUnit class for comment_excerpt(), covering display output, comment objects, the global comment fallback, and the display filter.

Test-only; no production code changes.

Why

comment_excerpt() had no direct @covers coverage. Small helper coverage fits the #65819 test cleanup track.

How

Add tests/phpunit/tests/comment/commentExcerpt.php with @covers ::comment_excerpt and @covers ::get_comment_excerpt.

Testing Instructions

1. npm run test:php -- --filter Tests_Comment_CommentExcerpt
2. npm run test:php -- --filter Tests_Comment_CommentExcerpt -c tests/phpunit/multisite.xml
3. npm run test:php -- --filter Tests_Comment_CommentExcerpt --order-by=random
4. npm run test:php -- --group comment

[lancewillett]

Please use the literal fixture text, Short comment excerpt text., as the expected output in the three unfiltered display tests. Calling get_comment_excerpt() to compute the expected result lets a regression in that same getter change both sides of the assertion. The fixture already tells us the intended output.

The tests pass locally in randomized single-site and multisite runs; this small change makes their oracle independent before landing.
