fix(windows): restore Bun auto-installation in smart-install.js

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

 /**
  * Smart Install Script for claude-mem
  *
- * Features:
- * - Detects execution context (cache vs marketplace directory)
- * - Installs dependencies where the hooks actually run (cache directory)
- * - Only runs npm install when necessary (version change or missing deps)
- * - Caches installation state with version marker
- * - Provides helpful Windows-specific error messages
- * - Cross-platform compatible (pure Node.js)
- * - Fast when already installed (just version check)
+ * Ensures Bun runtime and uv (Python package manager) are installed
+ * (auto-installs if missing) and handles dependency installation when needed.
