Spool Studio 3.1.0

Spool Studio now supports native NFC/RFID tag links in Spoolman 0.27.0 and later, while keeping existing Paxx12 SpoolLink installations compatible.

• Native tag owners take priority over stale card_uids entries. UID scans work without an OpenSpool payload. Filament tags are identified without automatically choosing a spool.
• Compatibility mode writes native links and the legacy card_uids field. Older Spoolman servers retain the legacy workflow.
• New per-server Native tags only setting for users with compatible printer firmware.
• Settings include a migration preview. Copy links while retaining the legacy field, or explicitly clear successfully migrated entries. Invalid, duplicate and conflicting entries remain for review; native owners are not moved by migration.
• Manage and unlink tag links from the selected spool. Explicit UID linking can move a native spool tag after confirmation; ordinary saves report ownership conflicts.
• Fixed New from selected losing Material modifier, including PETG 2.0. Duplicating also avoids reusing the original tag UID.
• Fixed the prerequisite message when the printer has no Paxx12 toolhead assignment command.

Keep compatibility mode enabled until your printer firmware supports native Spoolman tags. Clearing card_uids can break automatic detection in older firmware. Tag encoding is unchanged; OpenTag3D content support and external scanner subscriptions are separate features.
