Replace classname/name keyword guessing with real data so sit/lay/stand
has zero false positives:
- autoDetectInteraction() now accepts real flags (cansiton/canlayon/
canstandon), logicType, and animation-state count; real data wins and
keywords are only a fallback when no real data exists.
- New furni-real-interaction helper reads the local FurnitureData.json
(highest-revision entries win; a true flag in any duplicate is kept)
and falls back to the official Habbo furnidata.
- interaction_modes_count now uses emulator conventions: dice=6,
gate/teleport=2, roller=1, generic multistate = animation-state count,
chairs/beds=1, plain items=0.
- verifyAndFixInteractionModesCount only touches items with real data
and skips everything else (no keyword overwrites).
- parseNitroBundle falls back to gunzip for gzip-compressed .nitro files.
- Wired through furni-import, upload-import, clone-import, and the nitro
editor auto-detect button.
