kata-new-project

<objective>

Initialize a new project with deep context gathering and workflow configuration.

This is the most leveraged moment in any project. Deep questioning here means better plans, better execution, better outcomes.

**Creates:**
- `.planning/PROJECT.md` — project context
- `.planning/config.json` — workflow preferences

**After this command:** Run `/kata:kata-add-milestone` to define your first milestone.

## Phase 1: Setup

**MANDATORY FIRST STEP — Execute these checks before ANY user interaction:**

1. **Abort if project exists:**
   ```bash
   [ -f .planning/PROJECT.md ] && echo "ERROR: Project already initialized. Use /kata:kata-track-progress" && exit 1
   ```

2. **Initialize git repo in THIS directory** (required even if inside a parent repo):
   ```bash
   if [ -d .git ] || [ -f .git ]; then
       echo "Git repo exists in current directory"
   else
       git init
       echo "Initialized new git repo"
   fi
   ```

3. **Detect existing code (brownfield detection):**
   ```bash
   CODE_FILES=$(find . -name "*.ts" -o -name "*.js" -o -name "*.py" -o -name "*.go" -o -name "*.rs" -o -name "*.swift" -o -name "*.java" 2>/dev/null | grep -v node_modules | grep -v .git | head -20)
   HAS_PACKAGE=$([ -f package.json ] || [ -f requirements.txt ] || [ -f Cargo.toml ] || [ -f go.mod ] || [ -f Package.swift ] && echo "yes")
   HAS_CODEBASE_MAP=$([ -d .planning/codebase ] && echo "yes")
   ```

   **You MUST run all bash commands above using the Bash tool before proceeding.**

## Phase 2: Brownfield Offer

**If existing code detected and .planning/codebase/ doesn't exist:**

Check the results from setup step:
- If `CODE_FILES` is non-empty OR `HAS_PACKAGE` is "yes"
- AND `HAS_CODEBASE_MAP` is NOT "yes"

Use AskUserQuestion:
- header: "Existing Code"
- question: "I detected existing code in this directory. Wou
