Native NeoForge support via Forgified Fabric API #4810

I would like to be able to..

Run Plan natively on NeoForge dedicated servers (not only via SpongeForge), using Forgified Fabric API so the existing Fabric event/mixin surface can be shared.

Is your feature request related to a problem? Please describe.

Issue #4162 asked for NeoForge support and was closed pointing at SpongeForge API 14. That covers Sponge-on-(Neo)Forge, but not a native NeoForge jar for modded backends (e.g. Velocity + NeoForge backends) where Fabric/Sponge are not present.

Proposed approach

• New Plan/neoforge module targeting Minecraft 26.2 (same line as current Fabric)
• Separate PlanNeoForge-*.jar (same packaging pattern as Fabric)
• Depend on FFAPI at runtime (fabric_api); do not use Sinytra Connector to load the Fabric jar
• Note: FFAPI has no 26.2 release yet — first implementation uses FFAPI 26.1.2 as a stand-in until Sinytra ships 26.2

A draft PR will follow from Magi1053/Plan.
