[dependabot]

Bumps github.com/zclconf/go-cty from 1.18.1 to 1.19.0.

Changelog

Sourced from github.com/zclconf/go-cty's changelog.

1.19.0 (July 6, 2026)

• When building with Go 1.27 or later, the various string operations that are defined in terms of UAX#29 grapheme cluster segmentation will now use the Unicode 17 character properties and rules. For older versions of Go, Unicode 15 is still used.
• The cty.ValueMarks type, which represents a set of value marks separately from any value, now has method Has for concisely testing if a specific mark is present, and Insert for inserting elements from an iter.Seq[any] into an existing set of marks for easier gradual construction without creating any temporary mark sets.
