Subject: [PATCH] style: use compact Unicode symbols instead of emoji in CLI
 output
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds AGENTS.md with CLI output style guideline: prefer compact Unicode
symbols (✓ ✗ ● ○ —) over emoji for consistent terminal rendering.

Replaces all emoji in the stack module (setup.py, pre-push.sh) with
the compact symbols to match the queue module's existing style.

+# Agent Instructions
+
+## CLI Output Style
+
+Use compact Unicode symbols for terminal output, not emoji. This keeps new and
+updated terminal output consistent and avoids rendering issues across terminals.
+
+**Preferred symbols:**
+- `✓` success, approved, merged
+- `✗` failure, conflict, changes requested
+- `●` active, pending, in progress
+- `○` inactive, skipped, none
+- `—` unknown, not applicable
+
+**Avoid in terminal output:** `✅`, `❌`, `🟢`, `🔴`, `📝`, `⚠️`, `🔄`, `📦`, `🤖`, `🔗`
+and other emoji. They can render at inconsistent widths across terminals and
+break column alignment.
+
+**Exception:** Emoji are acceptable in markdown output destined for GitHub
+(PR comments, CI summaries) where they render consistently.
