Progressive Portals

Changed — Portal Denial & Safe Teleport Behavior

• Nether Portals Stay Lit on Deny: Removed the portal-breaking mechanic when a player is denied entry, so Nether portals remain lit instead of shattering.
• 2-Block Portal Clearance: Safe return locations must now be at least 2 blocks horizontally away from the portal blocks themselves (nether_portal, end_portal, and end_gateway), ignoring the obsidian or end portal frame.

Added — Smart Ground History & Approach-Side Relocation

• 10-Block Solid Ground History: Tracks each player's last 10 valid solid ground positions (and checks the 1-block surrounding area around each stored spot) so denied players always have a reliable, hazard-free return point.
• Approach-Side Preference: Tracks the direction a player entered the portal from and prioritizes teleporting them back to a safe block on the same side of the portal they walked in from.
• Fallback Safe-Spot Search: Added a multi-ring fallback search around the portal if a player has no recorded ground history yet (such as right after respawning or teleporting), preventing players from standing inside a lit portal to bypass progression checks.
