PatchLib - Bug Fixes, Crash Fixes & Mod Compat

PatchLib 1.1.0

New fixes

• Sable / Create Aeronautics: fixes the cause of Rapier native panic: No center of mass for body!. A physics sub-level without solid blocks reached the physics engine with no mass data and crashed the next physics tick (sable.null_center_of_mass, sable.null_center_of_mass_native).
• Sable, safety net: when a physics panic still arrives as a Java exception, the server stays up. PatchLib repairs the state Sable leaves behind and runs Sable's own sub-level recovery (sable.physics_panic_guard).
• Wetland Whimsy (below 2.0.4): pot patterns were registered twice, which aborted RegisterEvent and rolled every registry back to vanilla (wetlandwhimsy.pot_pattern_dupe).
• VanillaBackport on Arclight: fixes the startup crash from ThrownEggMixin. PatchLib takes that one mixin off and sets the chicken variant itself (vanillabackport.arclight_thrown_egg).
• Blueprint on Arclight: fixes the crash on the first structure load. PatchLib disarms only the broken StructureStart injector and feeds Blueprint's repaletters from a spot that still exists (blueprint.arclight_piece_repaletters).

New opt-in tools (off by default)

• debug.connection_probe (server): logs every player's connection state once a second, for "player freezes, then times out" problems.
• sleep.entity_resync (server): re-sends mob positions while someone sleeps, so clients stop drawing mobs in the wrong place.
• client.desync_snap (client): snaps entities that drifted more than 2 blocks back to their server position.
• client.sleep_desync_probe (client): measures packet delay and entity drift on the client and prints a verdict.
• /patchlib testpanic [ticks] (operators): makes physics ticks fail on purpose to prove the Sable safety net works.

Changes

• Diagnostics and experiments are now opt-in. A fresh config gets them as false, marked "Opt-in". Existing configs keep every value already set, and new patches are added on update.
• The startup log shows the actual PatchLib version.
• 24 fixes plus 4 opt-in tools, up from 18 fixes.
