Add complete spell visual pipeline resolving the DBC chain (Spell → SpellVisual → SpellVisualKit → SpellVisualEffectName → M2) with precast/cast/impact phases, bone-attached positioning, and automatic dual-hand mirroring. Ribbon rendering fixes: - Parse visibility track as uint8 (was read as float, suppressing all ribbon edges due to ~1.4e-45 failing the >0.5 check) - Filter garbage emitters with bone=UINT_MAX unconditionally - Guard against NaN spine positions from corrupt bone data - Resolve ribbon textures via direct index, not textureLookup table - Fall back to bone 0 when ribbon bone index is out of range Particle rendering fixes: - Reduce spell particle scale from 5x to 1.5x (was oversized) - Exempt spell effect instances from position-based deduplication Spell handler integration: - Trigger precast visuals on SMSG_SPELL_START with server castTimeMs - Trigger cast/impact visuals on SMSG_SPELL_GO - Cancel precast visuals on cast interrupt/failure/movement M2 classifier expansion: - Add AmbientEmitterType enum for sound system integration - Add 20+ foliage tokens, 4 spell effect tokens, isSmallFoliage flag - Add markModelAsSpellEffect() to override disableAnimation DBC layouts: - Add SpellVisualID field to Spell.dbc for all expansion configs Signed-off-by: Pavel Okhlopkov <pavel.okhlopkov@flant.com>
