feat: map confirmation isNonConsequential in AI capabilities extension

[sebastienlevert]

Description

The x-ai-capabilities confirmation object supports isNonConsequential (plugin manifest 2.4, available in Microsoft.DeclarativeAgents.Manifest as Confirmation.IsNonConsequential), but Kiota was silently dropping it:

• ExtensionConfirmation (the x-ai-capabilities parser model) only had Type/Title/Body.
• ParseConfirmation / WriteConfirmation never read or wrote isNonConsequential.
• PluginsGenerationService.GetFunctionCapabilitiesFromCapabilitiesExtension mapped only Type/Title/Body onto the generated manifest Confirmation.

As a result, a function could never be marked non-consequential in the generated plugin manifest, so the "Always Allow" confirmation option was unavailable.

Changes

• OpenApiAiCapabilitiesExtension.cs: add IsNonConsequential to ExtensionConfirmation; parse it (boolean) in ParseConfirmation; emit it in WriteConfirmation.
• PluginsGenerationService.cs: map capabilities.Confirmation.IsNonConsequential → Confirmation.IsNonConsequential.
• Tests: extended the OpenApiAiCapabilitiesExtension parse + write round-trip tests and the end-to-end GeneratesManifestWithAiCapabilitiesExtensionAsync generation test to cover isNonConsequential.

Example

OpenAPI operation extension:

x-ai-capabilities:
  confirmation:
    type: AdaptiveCard
    title: Fill color
    body: Change the cell color?
    isNonConsequential: true

now produces in the generated plugin manifest:

"capabilities": {
  "confirmation": { "type": "AdaptiveCard", "title": "Fill color", "body": "Change the cell color?", "isNonConsequential": true }
}

Testing

• dotnet test tests/Kiota.Builder.Tests/Kiota.Builder.Tests.csproj --filter "FullyQualifiedName~OpenApiAiCapabilitiesExtension|FullyQualifiedName~PluginsGenerationService" → 96 passing, 0 failing.

Context

Complements the TypeSpec authoring side (@microsoft/typespec-m365-copilot) which emits x-ai-capabilities.confirmation.isNonConsequential — see microsoft/typespec-copilot-skills#530. The underlying manifest model already supports the property (Microsoft.DeclarativeAgents.Manifest@5.0.0-rc.2); this PR wires Kiota's generator to populate it.

Pull request overview

This PR ensures the x-ai-capabilities.confirmation.isNonConsequential flag is preserved end-to-end: parsed from the OpenAPI extension, re-serialized when needed, and mapped into the generated plugin manifest Confirmation so non-consequential confirmations enable the “Always Allow” UX.

Changes:

• Added IsNonConsequential to the x-ai-capabilities confirmation model and implemented parse/write support.
• Mapped capabilities.Confirmation.IsNonConsequential into the generated plugin manifest confirmation object.
• Extended unit + end-to-end tests and documented the change in the changelog.
