Summary

Related issue: #____

What changed?

• Removed the lingering NetBeans template headers from the public NIP helper and factory classes to cut boilerplate noise.
• Expanded JavaDoc across the WebSocket client support utilities so their responsibilities and error paths are explicit.
• Documented BaseTagFactory#create to describe JSON decoding failures surfaced to callers.

BREAKING

None.

Review focus
