Debanjum c6670e815a Drop Server Side Indexer, Native Offline Chat, Old Migration Scripts (#1212)
### Overview
Make server leaner to increase development speed. 
Remove old indexing code and the native offline chat which was hard to
maintain.

- The native offline chat module was written when the local ai model api
ecosystem wasn't mature. Now it is. Reuse that.
- Offline chat requires GPU for usable speeds. Decoupling offline chat
from Khoj server is the recommended way to go for practical inference
speeds (e.g Ollama on machine, Khoj in docker etc.)

### Details
- Drop old code to index files on server filesystem. Clean cli, init
paths.
- Drop native offline chat support with llama-cpp-python. 
  Use established local ai APIs like Llama.cpp Server, Ollama, vLLM etc.
- Drop old pre 1.0 khoj config migration scripts
- Update test setup to index test data after old indexing code removed.
