v0.4.0 — Instant Search & Persistent Cache

Highlights

⚡ Instant Search (was: minutes → now: milliseconds)

• Full ROM file index cached to disk
• Search works from memory — no more filesystem walking
• 86 systems, 100K+ ROMs indexed in one scan

💾 Persistent Discovery Cache

• First startup: scans and saves to /media/fat/config/misterclaw_cache.json
• Subsequent starts: loads from cache instantly — no scanning at all
• Two-phase discovery: fast folder scan first, detailed scan in background

🔄 New Commands

• rescan — Re-scan ROM library, optionally for a specific drive (--location usb0)
• reload — Reload current core to apply config changes
• cfg-write now returns reload_required: true instead of auto-reloading

🕹️ 15 MCP Tools

Two new tools: mister_reload, mister_rescan
