ColonyLink

## v1.1.2 — Multi-Builder

### New Features

- **Multi-Builder support** — the Wand can now be linked to up to 5 Builder's Huts simultaneously
- **Tabbed GUI** — bookmark-style tabs on the left side of the panel, one per linked builder
- Active tab: brighter, pulled forward
- Inactive tabs: darker, gear icon with mouseover tooltip (builder name + coordinates)
- Orange tab = no Redirector paired yet
- **"+" button** — closes the GUI and prompts pairing mode for a new builder
- **Unlink button** — removes the active builder tab from the Wand (Redirector unaffected)
- Each builder has its own independent Redirector, resources, crafting, and warehouse scan

### Improvements
- Builder name on tabs auto-updates when a citizen is assigned (no more N/A)
- Send/Send All buttons are now greyed out when the Redirector is missing or broken
- GUI closes automatically when the last builder is unlinked
- Clear error message when trying to pair a Redirector already used by another builder
- Colony permission check: players without ACCESS_HUTS cannot link or view another colony's builders
- Ticker sends a proper reset packet when a Redirector or Builder's Hut is destroyed

### Bug Fixes
- Fixed legacy NBT format (`redirector_x/y/z`) still being read by SendToBuilderHandler and WarehouseScanHandler
- Fixed wand stack copy desync in useOn (now reads from actual inventory slot)
- Fixed "No Redirector linked" spam after Unlink

### Migration
- Existing v1.1.1 wands are automatically migrated to the new multi-builder NBT format on first use

## Roadmap
| v1.1.3 |   RF energy system — passive RF consumption on Wand, per-craft RF cost |
