feat: PR screenshots in /ship template + upload/auth tests

Adds Step 6.75 to /ship: detects frontend scope, offers responsive screenshots, handles auth inline, captures via browse, uploads to gstack.gg, embeds watermarked images in PR body. Tests cover screenshot-upload (usage, missing file, auth check, slug sanitization) and gstack-auth device code flow (happy path, expired, invalid secret, SSH fallback).

+## Step 6.75: PR Screenshots (optional)
+
+Check if this PR includes frontend/UI changes:
+
+```bash
+source <(~/.claude/skills/gstack/bin/gstack-diff-scope <base> 2>/dev/null) || true
+echo "SCOPE_FRONTEND: ${SCOPE_FRONTEND:-false}"
+```
+
+If `SCOPE_FRONTEND=true`, check if the browse binary is available:
+
+```bash
+_ROOT=$(git rev-parse --show-toplevel 2>/dev/null)
+B=""
+[ -n "$_ROOT" ] && [ -x "$_ROOT/.claude/skills/gstack/browse/dist/browse" ] && B="$_ROOT/.claude/skills/gstack/browse/dist/browse"
+[ -z "$B" ] && B=~/.claude/skills/gstack/browse/dist/browse
+[ -x "$B" ] && echo "BROWSE_READY" || echo "BROWSE_NOT_AVAILABLE"
+```
+
+If both frontend scope AND browse are available, use AskUserQuestion:
+
+> This PR changes frontend code. Want to add screenshots to the PR? Your screenshots
+> will get a "Screenshots · GStack" watermark — free visual evidence in your PR.
+>
+> A) Responsive screenshots (mobile + tablet + desktop) — recommended
+> B) Single desktop screenshot
+> C) Skip screenshots
+
+If the user chooses A or B:
+
+1. **Check authentication:**
+   ```bash
+   ~/.claude/skills/gstack/bin/gstack-auth-refresh --check 2>/dev/null
+   ```
+   If not authenticated, run `~/.claude/skills/gstack/bin/gstack-auth` inline. Wait for completion.
+
+2. **Detect app URL:**
+   Read CLAUDE.md and look for an `app_url` or `dev_url` setting. If not found, use
+   AskUserQuestion: "What URL should I screenshot? (e.g., http://localhost:3000)"
+   Persist the answer to CLAUDE.md under a `## Screenshots` section so we never ask again.
+
+3. **Capture screenshots:**
+   For option A (responsive):
+   ```bash
+   $B goto <url>
+   $B responsive /tmp/gstack-pr-screenshots
+   ```
+   For option B (single):
+   ```bash
+   $B goto <url>
+   $B screenshot /tmp/gstack-pr-screenshots/desktop.png
+   ```
+
+4. **Upload each screenshot:**
+   ```bash
+   REPO_SLUG=$(basename "$(git rev-parse --show-toplevel 2>/dev/null)")
+   BRANCH=$(git branch --show-current 2>/dev/null)
+   for img in /tmp/gstack-pr-screenshots/*.png; do
+     VIEWPORT=$(basename "$img" .png)
+     URL=$(~/.claude/skills/gstack/bin/gstack-screenshot-upload "$img" \
+       --repo-slug "$REPO_SLUG" --branch "$BRANCH" --viewport "$VIEWPORT")
+     echo "SCREENSHOT_URL[$VIEWPORT]=$URL"
+   done
+   ```
+
+5. **Store proxy URLs** for use in Step 8's PR body.
+
+**Failure handling:** If any step fails (browse unavailable, auth fails, upload fails),
+warn in output and continue without screenshots. Never block /ship for screenshot failures.
+
+If `SCOPE_FRONTEND=false` or browse is not available, skip this step silently.
