Fix bug in attribute selector parsing

[RobinMalfait]

This PR fixes a bug in the selector parser where an attribute selector followed by a type selector inside a compound selector resulted in the wrong result.

Given you have this CSS:

[data-foo]div {}

Then parsing it before this PR, would result in:

{
  kind: 'compound',
  nodes: [
    { kind: 'selector', value: '[data-foo]div' },
  ],
},

But with this PR, it's properly split:

{
  kind: 'compound',
  nodes: [
    { kind: 'selector', value: '[data-foo]' },
    { kind: 'selector', value: 'div' },
  ],
},

I also tweaked some of the comments in the parser that are unrelated, but I was there already.

Test plan

1. Added a regression test
2. All other tests should pass

Confidence Score: 5/5

Safe to merge — the fix is a minimal, well-targeted one-line change to the attribute selector branch of the parser, backed by three new regression tests.

The change replaces a single assignment (buffer += ...) with a direct append(selector(...)) call, exactly scoping the fix to the broken code path. Existing tests still pass, and the new tests cover the reported case and adjacent variants. No other logic in the parser is disturbed.

No files require special attention.

Walkthrough

This PR changes selector parsing so attribute selectors are emitted as their own selector nodes from the input slice, rather than being merged into the current buffer. It also refreshes inline comments in the parser, updates tests for compound selectors with adjacent attribute and type selectors, and adds a changelog entry for the parsing fix.
