Npcsh

-broke out the provider-specific llm_funcs into 4 separate files:


1. stream,
2. response
3. conversation
4. embeddings

-deprecated NPCSH_MODEL and NPCSH_PROVIDER in favor of NPCSH_CHAT_MODEL and NPCSH_CHAT_PROVIDER and more specifically integrated in other ENV variables for reasoning, image gen, image analysis, and embeddings.


-fixed a couple bugs here and there (including the one identified in 80 )

-re-factored tools to work with arbitrary steps
-this is a change that breaks old tools. if you happen to have some from before, please remove all of them in your npcsh directory

`rm ~/.npcsh/npc_team/tools/*.tool`

and then start npcsh and it should be good

-fixed gemini conversationos for spool

-added some plonk stuff, more readme updates

-last version of v0.2!!!!!! next up will be v0.3.1. v0.3 will likely focus a lot on pipelines/sql/mcp.
