_⚠️ Potential issue_ | _🟡 Minor_

**Add language identifiers to fenced code blocks (MD040).**

Line 480 and Line 511 start fenced blocks without a language. Add a language (e.g., `text`) to satisfy markdownlint and improve readability.

````
In `@issues/plan-unix-style-migration.md` around lines 480 - 486, Two fenced code
blocks lack language identifiers (MD040); update the opening fences for the
ASCII diagram block that begins "Subtask 1 (Exit Codes) ──────────┐" and the
package tree block that begins
"packages/core/ai_content_pipeline/ai_content_pipeline/" to include a language
(e.g., change ``` to ```text) so markdownlint passes and readability improves;
ensure both occurrences (the diagram and the package tree) are updated.
