Nebula v0.0.17 - Onramping, Aggregations & Agent Improvements

This release introduces significant improvements to Nebula's agent capabilities, adding fiat onramping through Universal Bridge, new NFT collection tools, and aggregated transaction and events data. Improvements have been made to Nebula’s memory handling, leading to faster responses in some cases and helping us prepare for our next major release. Additionally, we fixed a major bug that caused Nebula to respond with "No response received, please try again" in long-running queries.

Nebula v0.0.17 is live now!
