Resolved bug when entire chat context is deleted and hypaV2Data becomes empty, throwing a undefined index error. Also changed it to typescript index.
Hopefully resolved issue where same chat is summarized over and over again by adding another field to mainChunks.
# Changelist:
## 1. Types
### MainChunks
Added id(int), and chatMemos(Set<string>)
Id: incremental int starting from 0
chatMemos: A set of UUID, containing which chat has been summarized in it.
### Chunks
mainChunkID: A connection of which mainChunk it has been split from
text: the split text data
## 2. Features
### CleanInvalidChunks
Called every time when chat is updated and Hypamemory is used.
Gets all the memo(UUID)s of current chats, and creates a set.
Then checks if each mainChunk's chatMemos set is subset of the enitre memo set. If not, the summarized part's chat is deleted/edited. The mainChunk is filtered out.
Concurrently, the chunks that are split from that mainChunk is also deleted.
Also revoked potentially problematic feature(add hypav2data chunk)
TODO:
1. On mid-context editing, currently that is not considered as deletion. Do have optional editedChatIndex to latter dive in more.
2. re-roll mainChunks(re-summarization) functionalities added, but not able to access it.
