Problem

After migrating to User Token, the Slack message poster is automatically the logged-in user, making the explicit Author display redundant.

Current Behavior

1. Share workflow to Slack
2. ❌ Message displays Author: @username and Date: 2025/12/1
3. ❌ OAuth requests unnecessary users:read scope

Expected Behavior

1. Share workflow to Slack
2. ✅ Poster is automatically shown in Slack's native poster field (due to User Token posting)
3. ✅ Only minimal required scopes are requested

Solution

Remove features that became unnecessary after User Token migration:

• Remove users:read scope from OAuth
• Remove getUserInfo() method from SlackApiService
• Remove Author/Date display blocks from Slack messages
• Remove Note message from import links

Changes

File: src/extension/services/slack-oauth-service.ts

• Remove users:read from userScopes

File: src/extension/services/slack-api-service.ts

• Remove getUserInfo() method entirely

File: src/extension/commands/slack-share-workflow.ts

• Remove Author-related variables and code
• Remove createdAt related code

File: src/extension/utils/slack-message-builder.ts

• Remove authorName, authorUserId, createdAt fields from interface
• Remove Author/Date block from message builder
• Remove Note message from import links section

Impact

• Slack messages become simpler and cleaner
• OAuth requested scopes are reduced (privacy improvement)
• No breaking changes

Testing

• Manual E2E testing completed
• Code quality checks passed (npm run format && npm run lint && npm run check)
• Build successful (npm run build)
