Remove TextCompletion and GenerateContent from InferenceOperationType and GEN_AI_OPERATION_NAMES

[Copilot]

InferenceOperationType carried two legacy genAI operation values (TextCompletion, GenerateContent) that are no longer emitted by the SDK. These were also present in the GEN_AI_OPERATION_NAMES allowlist used by partitionByIdentity to filter exportable spans.

Changes

• contracts.ts — Drops TEXT_COMPLETION and GENERATE_CONTENT from InferenceOperationType; enum now contains only CHAT.
• exporter/utils.ts — Removes 'TextCompletion' and 'GenerateContent' from the GEN_AI_OPERATION_NAMES allowlist.
• scopes.test.ts — Updates the one test using InferenceOperationType.TEXT_COMPLETION to use InferenceOperationType.CHAT.
• docs/design.md — Reflects the reduced enum.

// Before
export enum InferenceOperationType {
  CHAT = 'Chat',
  TEXT_COMPLETION = 'TextCompletion',   // removed
  GENERATE_CONTENT = 'GenerateContent'  // removed
}

// After
export enum InferenceOperationType {
  CHAT = 'Chat'
}

Original prompt

Create a PR in microsoft/Agent365-nodejs to remove the two genAI operation name strings TextCompletion and GenerateContent from the codebase.

Requirements:

• Search the whole repository for occurrences of these exact string literals (and any related usage that would break after removal):
  • 'TextCompletion' (commented as // InferenceOperationType.TEXT_COMPLETION)
  • 'GenerateContent' (commented as // InferenceOperationType.GENERATE_CONTENT)
• Remove them from any lists/sets/allowlists of genAI operation names (e.g., GEN_AI_OPERATION_NAMES in packages/agents-a365-observability/src/tracing/exporter/utils.ts).
• Ensure any logic that relied on these values is still correct, and update tests accordingly.
• Run formatting/lint/tests as appropriate for the repo.

Repository-specific review rules:

• Ensure no occurrences of keyword Kairo remain in any .js, .ts, .jsx, .tsx files touched; if found, remove/replace appropriately.
• Ensure all modified or new .js/.ts/.jsx/.tsx files contain the Microsoft MIT header at the top:
  // Copyright (c) Microsoft Corporation.
// Licensed under the MIT License.
  followed by a blank line.

Notes:

• The user specifically wants these two values removed "from the whole repos".

Context:

• Known location with these strings: packages/agents-a365-observability/src/tracing/exporter/utils.ts.
• The file already has the correct header; preserve it.

The following is the prior conversation context from the user's chat exploration (may be truncated):

User: create a PR remove from 'TextCompletion', // InferenceOperationType.TEXT_COMPLETION
'GenerateContent', // InferenceOperationType.GENERATE_CONTENT from the whole repos

Assistant: I’m waiting for your confirmation in the pending prompt so I can proceed with creating the pull request and applying the repo-wide removals.

Isn't this change going to break usage of older Semantic Kernel versions?
