Feature request: Access Slack 'Save for later' bookmarks via MCP

Feature Request

It would be very useful if Claude Code could access Slack's "Save for later" (bookmarked) messages through the Slack MCP integration.

Motivation

People commonly use Slack's "Save for later" as a lightweight task list — saving messages they need to follow up on, investigate, or act upon. Being able to ask Claude to review these saved items would enable workflows like:

• "Look at my saved Slack messages and help me triage them"
• "Summarize the tasks I've saved for later"
• "Help me work through my saved items one by one"

Current Limitation

The current Slack MCP tools (slack_search_public, slack_read_channel, etc.) don't provide access to the user's saved/bookmarked messages. The Slack API does support this via the stars.list endpoint (legacy) or the newer bookmarks API.

Suggested Solution

Add a tool like slack_list_saved_items or slack_list_reminders to the Slack MCP server that retrieves the authenticated user's "Save for later" items.
