SNR.FLY-STABLE-1.2

Fixes

• Fix legacy train data migration with Trinkets Updated (#9), preserving equipment and third-party NBT.
• Reduce block atlas usage by excluding 611 redundant connected-texture source sheets. Generated connected textures and original source assets are retained.
• Recover from block atlas packing failures by retrying at a lower mip level when necessary. Original texture resolution and global graphics settings remain unchanged; distant texture filtering may use fewer mip levels for that atlas reload.
• Fix deferred rendering of conductor equipment, whistle flags, semaphores and diesel smokestacks.
• Fix axial smokestack rotation during quarter-turn train disassembly.
• Read early datafixer and missing-track options from the current JSON configuration.
• Reject unsupported coupler, switch, buffer and whistle interactions on curved track with feedback.
• Sync server settings when joining, then restore local settings when disconnecting without overwriting client configuration files. Invalid synced settings are rejected or rolled back.
• Remove expensive whistle route diagnostics and repetitive INFO logging.
