Fix anchor reference regression in nested structures (#839)

* Add failing test for anchor reference regression

This test demonstrates a regression in v1.16.0 where anchors defined
in unmapped struct fields cannot be referenced using direct aliases
in nested map structures.

The test currently fails with:
  could not find alias \"base_url\"

This regression was introduced by PR #660 which removed the fallback
to anchorNodeMap when resolving aliases.

Test case:
- Anchor defined in 'shared' field (not mapped to struct)
- Direct alias reference in nested structure: defaults.http.url: *base_url
- This pattern works in v1.15.0 but fails in v1.16.0+

Note: Existing tests only cover merge keys (<<:) which still work.
This test covers direct alias references which are broken.

* Fix anchor reference regression in nested structures

This fixes the regression demonstrated by TestDecoder_AnchorInUnmappedField
where anchors defined in unmapped struct fields could not be referenced
using direct aliases in nested map structures.

* Remove redundant aliasName variable

As suggested by @goccy, eliminate the redundant aliasName variable
and use the existing text variable instead, which holds the same value.
