A secondary block comment could incorrectly set the indentation anchor for a standalone comment run, causing indentation to drift across formatter passes.

• Comment-run anchoring: Measure the minimum indentation from the first comment in each standalone group, while still traversing the remaining comment tokens.
• Regression coverage: Check that formatting this case preserves its indentation on repeated passes:

if ($a) {
    <# first
#> <# second #>
        # nested
}

What changed in this PR

This PR prevents indentation drift when repeatedly formatting standalone comment runs containing multiline block comments.

Changes:

• Calculate minimum indentation using only the first comment in each standalone group, while continuing to traverse all comment tokens.
• Add a regression test that verifies indentation remains unchanged across two formatter passes.

File	Description
