Attachment-only and Block Kit-only Slack messages returned empty CLI content.

• Extract attachment fields and nested or top-level block text when plain text is empty; retain plain-text and attachment precedence.
• Exercise the nested attachment fallback with empty text, nonempty text precedence, context/rich-text sections and mixed attachment/block messages.

Focused Slack message rendering package with race detection passed on office server 2 at 33fb919.

Correctness confidence: 85% from source inspection; focused remote Go checks passed. Merge risk: low for the rendering fallback; deployment risk is limited to messages previously rendered empty. The repository’s require-labels check passed with the required patch label.

Keep open for merge preparation: main still returns empty content for attachment-only and Block Kit-only messages.

• internal/slack/messages.go:387-395 adds a fallback only when plain text is empty, preserving existing plain-text output and the body limit.
• Add an empty-text nested-attachment-block regression: TestParseRawMessage_AttachmentNestedBlocks supplies non-empty text and therefore never exercises the fallback it is intended to cover. Include a rich-text context case and a message carrying both attachment and top-level blocks to define precedence.
• The latest require-labels check is failing; satisfy this repository’s actual check before merge.
• Estimated correctness confidence: 83%; merge risk: low after focused checks. Static source review only; Go tests were not run here. Deployment risk is limited to message rendering, and messages with non-empty fallback/stub text still intentionally omit attachment details.

Pushed fix: 33fb919.

Focused remote Go/rule checks remain pending. The description records the current confidence and merge/activation risks; remaining current-base integration and required checks still apply.
