feat(lora-stacker): conditionally update trigger words based on node mode

Add node mode checks to ensure trigger words are only updated when the stacker node is active (mode 0 for Always or mode 3 for On Trigger). This prevents unnecessary updates when the node is inactive (mode 2 for Never or mode 4 for Bypass), improving performance and ensuring trigger words reflect the actual active state of the node.

The changes include:
- Adding mode checks before updating active LoRA names in the stacker callback
- Modifying collectActiveLorasFromChain to only include active nodes
- Adding comments to clarify node mode behavior
