Create ADR from Investigations

Synthesize viable investigations into a concise proposed ADR.

Usage: When user says "create ADR for {feature-name}"

Instructions

1. Generate ADR number: Use format {YYMM} based on current date (e.g., 2512 for Dec 2025)

2. Create ADR at docs/arch/adr-{YYMM}-{topic}.md:

# ADR-{YYMM}: {Title}

**Status**: Proposed
**Date**: {YYYY-MM-DD}
**Feature**: {feature-name}

## Context
{1-2 paragraphs: The problem from _feature.md, key constraints}

## Options Considered

1. **{Approach A}** - {one line summary} *(rejected: brief reason)*
2. **{Approach B}** - {one line summary} *(viable)*
3. **{Approach C}** - {one line summary} *(viable)*

## Decision

{1-2 paragraphs: What approach we chose and why. Reference the winning investigation(s).}

## Consequences

- {Impact on codebase}
- {What becomes easier}
- {What becomes harder or needs follow-up}

5. Keep it concise: No code snippets, no implementation checklists, no phase tracking. Just the decision and rationale.

6. Output: Show the ADR content and confirm next steps (implement, then accept ADR)

ADR Principles

• Context: Why we needed to decide (not how we'll implement)
• Decision: What we chose and why (not the full investigation details)
• Consequences: What changes as a result (both positive and negative)
