Add minimize-comment safe output type for GraphQL-based comment moderation

[Copilot]

Implements minimize-comment safe output allowing AI agents to hide comments on issues/PRs/discussions via GraphQL's minimizeComment mutation.

Implementation

Schema & Types

• schemas/agent-output.json: Added MinimizeCommentOutput with string comment_id (GraphQL node IDs only)
• pkg/parser/schemas/main_workflow_schema.json: Added minimize-comment configuration (max, target-repo, github-token)
• pkg/workflow/js/types/safe-outputs.d.ts: Added MinimizeCommentItem interface

JavaScript Implementation

• pkg/workflow/js/minimize_comment.cjs: GraphQL mutation with SPAM classifier, staged mode support
• pkg/workflow/js/minimize_comment.test.cjs: 8 unit tests covering all scenarios
• pkg/workflow/js/safe_outputs_tools.json: Tool signature emphasizing GraphQL node ID requirement

Go Integration

• pkg/workflow/minimize_comment.go: Job builder with MinimizeCommentConfig, uses shared config types and buildSafeOutputJob helper
• pkg/workflow/compiler_types.go: Added MinimizeComment to SafeOutputsConfig
• pkg/workflow/compiler_jobs.go: Job builder integration with detection job dependency
• pkg/workflow/safe_outputs.go: Tool filtering and enablement
• pkg/workflow/scripts.go: Script registration

Test Workflows

• pkg/cli/workflows/test-copilot-minimize-comment.md: Test workflow for Copilot engine
• pkg/cli/workflows/test-claude-minimize-comment.md: Test workflow for Claude engine
• pkg/cli/workflows/test-codex-minimize-comment.md: Test workflow for Codex engine
• .github/workflows/smoke-codex.md: Added minimize-comment to smoke test workflow

Permissions

Uses NewPermissionsContentsReadIssuesWritePRWriteDiscussionsWrite() matching the full scope (issues, PRs, discussions).

Usage

safe-outputs:
  minimize-comment:
    max: 5
    target-repo: owner/repo  # optional

// Agent output (JSONL)
{
  "type": "minimize_comment",
  "comment_id": "IC_kwDOABCD123456"  // GraphQL node ID (string only)
}

Key Design Decisions

String-only comment_id: GraphQL node IDs are always strings (e.g., IC_kwDOABCD123456). Numeric REST API comment IDs cannot be converted to GraphQL node IDs, so schema explicitly rejects numbers to prevent confusion.

SPAM classifier: Uses SPAM classifier for the minimizeComment mutation, appropriate for moderation use cases.

Original prompt

Create "minimize-comment" safe output type that allows the agent to minimize a comment.

• implemented with graphql

/**
 * Hide (minimize) a comment using the GraphQL API.
 */
export async function minimizeComment(
  octokit: ReturnType<typeof github.getOctokit>,
  nodeId: string
): Promise<void> {
  const query = /* GraphQL */ `
    mutation ($nodeId: ID!) {
      minimizeComment(input: { subjectId: $nodeId, classifier: SPAM }) {
        minimizedComment {
          isMinimized
        }
      }
    }
  `

  await octokit.graphql(query, { nodeId })
}

Done in commit decede3:

• ✅ Test workflows already in pkg/cli/workflows (test-copilot-minimize-comment.md, test-claude-minimize-comment.md, test-codex-minimize-comment.md)
• ✅ Added minimize-comment to smoke-codex.md safe-outputs
• ✅ ScriptRegistry already registered minimize_comment (scripts.go line 55, 153)
