1. Fixed offhand F-key dupe bug

The SWAP_OFFHAND (F key) protection was only blocking swaps in container inventories, not the player's own inventory. When a gem was in offhand and you pressed F on an item in your
inventory, the swap went through — duping the item and destroying the gem. Removed the isPlayerInventory gate so the swap is blocked in ALL inventory contexts when a gem is involved.

2. Toggle click now also blocks F-key abilities

Added a check for isClickActivationEnabled() in the swap hand listener. When toggle_click is disabled, the F key swap is still cancelled (gem stays safe), but no abilities are triggered. This matches the behavior of right-click abilities when toggle_click is off.

3. Reworked Astra secondary ability — Astral Projection

Replaced the 5-block teleport with spectator mode scouting:

• Player enters spectator mode for 10 seconds (configurable in abilities.durations.astra-projection)
• 8 chunk radius (128 blocks) boundary from origin — if the player goes beyond, they're teleported back to origin with a warning
• Cannot teleport to other players — SPECTATE teleport cause is blocked in TeleportListener.java
• After duration expires (or manual toggle), player is teleported back to their original location and game mode is restored
• Ghost particles appear at the origin body while projecting
• 3-second countdown warning before it ends
