CRITICAL FIX: v7.1.0 Bun auto-install broken on Windows 11
Problem:
- hooks.json calls `bun smart-install.js` but if Bun isn't installed,
command fails immediately with "bun is not recognized"
- smart-install.js never runs, so Bun never gets installed
- Chicken-and-egg problem
Root Cause:
- v7.1.0 removed Bun/uv auto-installation logic from smart-install.js
- Assumed Bun would already be available
- Breaks fresh installations on all platforms
Solution:
1. Changed SessionStart hook to use `node` for smart-install.js
(Node.js always available in Claude Code)
2. Restored Bun auto-installation logic:
- isBunInstalled() - check if Bun is in PATH
- installBun() - auto-install via PowerShell (Windows) or curl (Unix/macOS)
- Also restored uv auto-installation for Chroma
After Fix:
- smart-install.js runs with node (always available)
- Detects if Bun is missing and auto-installs it
- Subsequent hooks use bun successfully
- Works on fresh Windows installations
Fixes: User report from Discord - Windows 11 'bun' is not recognized
