Implements a new MCP tool that constructs Slack permalinks from channel IDs and message timestamps. This enables Claude to provide clickable links when referencing Slack messages, which is valuable for daily summaries, citations, and quick navigation.
Changes:
- Added FormatPermalinkTimestamp() helper to text_processor.go
- Added GetPermalinkHandler() and permalinkParams to conversations.go
- Registered get_permalink tool in server.go with required parameters
The tool accepts channel_id and message_ts, fetches the workspace name via AuthTest, and constructs the permalink in format:
https://{workspace}.slack.com/archives/{channel_id}/p{timestamp_without_dot}
