Rocket Restock

**Longer version (for a mod page/listing):**

Rocket Restock keeps your hotbar topped up automatically. Assign a hotbar slot, and whenever its item count drops to your threshold (default: 2 or fewer, or empty), the mod scans the rest of your inventory for shulker boxes and pulls more in — no digging through boxes mid-elytra-flight.

**Features:**
- Watch any hotbar slot for any item (defaults to Firework Rocket)
- Refills from any shulker box — main inventory, other hotbar slots, or offhand
- Never blends firework rocket flight durations — matches what's already in the slot, or lock it to a specific duration (short/medium/long)
- Adjustable threshold and target item, all via commands
- Fully server-side — works in singleplayer and on any server running the mod, no client install needed

**Commands:** `/rocketrestock watch`, `unwatch`, `list`, `threshold <n>`, `item <id>`, `duration <1-3|any>`

**Requires:** Minecraft 1.21.11, Fabric Loader 0.19.3+, Fabric API
