Pr

Create a pull request for current branch targeting the repo's base branch.

## What to do

1. Determine which repo — if the user mentions a managed repo (listed in `egregore.json` → `repos[]`), create the PR there. Otherwise use the hub.
2. Resolve the target base branch:
   - **Egregore hub repo**: always `develop`
   - **Managed repos**: read `base_branch` from `egregore.json` repos[] config (default `"develop"`)
     ```bash
     BASE_BRANCH=$(jq -r --arg name "$REPO" '(.repos[]? // empty) | select((if type == "object" then .name else . end) == $name) | if type == "object" then .base_branch // "develop" else "develop" end' egregore.json)
     ```
3. Summarize branch changes vs base branch
4. Prompt for title and description
5. Create PR via GitHub CLI: `gh pr create --base "$BASE_BRANCH"`
6. Track PR in graph (fire-and-forget):
   ```bash
   PROJ_HASH=$(echo -n "$(pwd)" | md5 2>/dev/null || echo -n "$(pwd)" | md5sum 2>/dev/null | cut -d' ' -f1)
   SID=$(cat "$HOME/.egregore/session-${PROJ_HASH}.id" 2>/dev/null || echo "")
   GH_USER=$(jq -r '.github_username // empty' .egregore-state.json 2>/dev/null)
   REPO_NAME=$(jq -r '.repo_name // "egregore"' egregore.json 2>/dev/null)
   bash bin/graph-op.sh create-pr "$SID" "$PR_NUMBER" "$REPO_NAME" "$GH_USER" "$PR_TITLE" 2>/dev/null &
   ```
   Where `$PR_NUMBER` is extracted from the `gh pr create` output URL.
7. Return PR URL
8. Do NOT auto-merge — explicit `/pr` means "please review this"
