chore(deps): bump github.com/zclconf/go-cty from 1.15.0 to 1.17.0

[dependabot]

Bumps github.com/zclconf/go-cty from 1.15.0 to 1.17.0.

Release notes

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

v1.17.0

cty now requires Go 1.23 or later.

• cty.Value.Elements offers a modern iter.Seq2-based equivalent of cty.Value.ElementIterator.

• cty.DeepValues offers a modern iter.Seq2-based equivalent of cty.Walk.

• cty.Value.WrangleMarksDeep allows inspecting and modifying individual marks throughout a possibly-nested data structure.

  Having now got some experience using marks more extensively in some callers, it's become clear that it's often necessary for different subsystems to be able to collaborate using independent marks without upsetting each other's assumptions. Today that tends to be achieved using hand-written transforms either with cty.Transform or cty.Value.UnmarkDeepWithPaths/cty.Value.MarkWithPaths, both of which can be pretty expensive even in the common case where there are no marks present at all.

  This new function allows inspecting and transforming marks with far less overhead, by creating new values only for parts of a structure that actually need to change and by reusing (rather than recreating) the "payloads" of the values being modified when we know that only the marks have changed.

• cty.ValueMarksOfType and cty.ValueMarksOfTypeDeep make it easier to use type-based rather than value-based mark schemes, where different values of a common type are used to track a specific kind of relationship with multiple external values.

• cty.Value.HasMarkDeep provides a "deep" version of the existing cty.Value.HasMark, searching throughout a possibly-nested structure for any values that have the given mark.

• cty.Value.UnmarkDeep and cty.Value.UnmarkDeepWithPaths are now implemented in terms of cty.Value.WrangleMarksDeep, so they benefit from its reduced overhead. In particular they avoid reconstructing a data structure that contains no marked values at all.

• cty.Value.MarkWithPaths now has a fast path when it's given a zero-length PathValueMarks, in which case it just returns the value it was given with no modifications.

v1.16.0

• convert: When converting between two different capsule types, will now try to use the "conversion from" implementation from the target type if the source type doesn't have a suitable "conversion to" implementation. (#194)
• convert: When converting to a map whose element type is an object type with optional attributes, will no longer construct a broken result when a final map is empty. (#198)

1.17.0 (September 5, 2025)

1.16.4 (August 20, 2025)

• cty.UnknownAsNull now accepts marked values and preserves the given marks in its result. Previously it had no direct support for marks and so would either panic or return incorrect results when given marked values.

1.16.3 (May 16, 2025)

• convert: Now generates more specific error messages in various cases of type conversion failure, giving additional information about the type that was given as compared to the type that was wanted by the caller.

1.16.2 (January 21, 2025)

• json: ImpliedType now returns an error if a JSON object contains two properties of the same name. As a compatibility concession it allows duplicates whose values have the same implied type, since it was unintentionally possible to combine ImpliedType and Unmarshal successfully in that case before, but this is not an endorsement of using duplicate property names since that makes the input ambiguous in any case. (#199)
• function/stdlib: ElementFunc no longer crashes when asked for a negative index into a tuple. This fixes a miss in the negative index support added back in v1.15.0. (#200)

1.16.1 (January 13, 2025)

• cty: Value.HasElement now treats unknown set elements consistently with how much of the rest of cty treats them.
• function/stdlib: FormatFunc and FormatListFunc now handle unknown and null values of unknown type as arguments, rather than letting the function system's short-circuit behavior take care of it. This allows cty.DynamicVal and cty.NullVal(cty.DynamicPseudoType) to be treated consistently with other values, returning results consistent with the documented behavior, rather than forcing the function to immediately return cty.DynamicVal.

1.16.0 (January 3, 2025)

• convert: When converting between two different capsule types, will now try to use the "conversion from" implementation from the target type if the source type doesn't have a suitable "conversion to" implementation. (#194)
• convert: When converting to a map whose element type is an object type with optional attributes, will no longer construct a broken result when a final map is empty. (#198)

1.15.1 (November 26, 2024)

• function: Function calls can now return more mark-related information when called with unknown values when neither AllowMarks nor AllowUnknown are set for a particular parameter. (#196)
