8ca39a436c Use llama.cpp for offline chat models
- Benefits of moving to llama-cpp-python from gpt4all:
  - Support for all GGUF format chat models
  - Support for AMD, Nvidia, Mac, Vulcan GPU machines (instead of just Vulcan, Mac)
  - Supports models with more capabilities like tools, schema
    enforcement, speculative ddecoding, image gen etc.
- Upgrade default chat model, prompt size, tokenizer for new supported
  chat models

- Load offline chat model when present on disk without requiring internet
  - Load model onto GPU if not disabled and device has GPU
  - Load model onto CPU if loading model onto GPU fails
  - Create helper function to check and load model from disk, when model
    glob is present on disk.

    `Llama.from_pretrained' needs internet to get repo info from
    HuggingFace. This isn't required, if the model is already downloaded

    Didn't find any existing HF or llama.cpp method that looked for model
    glob on disk without internet

1105d8814f Use cross-encoder to rerank search results by default on GPU machines
Latest sentence-transformer package uses GPU for cross-encoder. This
makes it fast enough to enable reranking on machines with GPU.

Enabling search reranking by default allows (at least) users with GPUs
to side-step learning the UI affordance to rerank results
(i.e hitting Cmd/Ctrl-Enter or ENTER).

Short-circuit API rate limiter for unauthenticated users ()
### Major
- Short-circuit API rate limiter for unauthenticated user
  Calls by unauthenticated users were failing at API rate limiter as it
  failed to access user info object. This is a bug.
  
  API rate limiter should short-circuit for unauthenicated users so a
  proper Forbidden response can be returned by API
  
  Add regression test to verify that unauthenticated users get 403
  response when calling the /chat API endpoint
  
### Minor

Push Files to Index from Emacs, Obsidian & Desktop Clients using Multi-Part Forms ()
### Overview
- Add ability to push data to index from the Emacs, Obsidian client
- Switch to standard mechanism of syncing files via HTTP multi-part/form. Previously we were streaming the data as JSON
  - Benefits of new mechanism
    - No manual parsing of files to send or receive on clients or server is required as most have in-built mechanisms to send multi-part/form requests
    - The whole response is not required to be kept in memory to parse content as JSON. As individual files arrive they're automatically pushed to disk to conserve memory if required
    - Binary files don't need to be encoded on client and decoded on server

### Code Details
### Major
- Use multi-part form to receive files to index on server
- Use multi-part form to send files to index on desktop client
- Send files to index on server from the khoj.el emacs client
  - Send content for indexing on server at a regular interval from khoj.el
- Send files to index on server from the khoj obsidian client
- Update tests to test multi-part/form method of pushing files to index

#### Minor
- Put indexer API endpoint under /api path segment
- Explicitly make GET request to /config/data from khoj.el:khoj-server-configure method
- Improve emoji, message on content index updated via logger
- Don't call khoj server on khoj.el load, only once khoj invoked explicitly by user
- Improve indexing of binary files
  - Let fs_syncer pass PDF files directly as binary before indexing
  - Use encoding of each file set in indexer request to read file 
- Add CORS policy to khoj server. Allow requests from khoj apps, obsidian & localhost
- Update indexer API endpoint URL to` index/update` from `indexer/batch`

0f993b332e Drop support for Ledger as a separate content type
Khoj will soon get a generic text indexing content type. This along
with a file filter should suffice for searching through Ledger
transactions, if required.

Having a specific content type for niche use-case like ledger isn't
useful. Removing unused content types will reduce khoj code to manage.

51dfa48e2b Have Khoj support Python 3.11 as Pytorch supports it now
- Previously Khoj could only support Python upto 3.10 due to pytorch.
  But lots of folks had python 3.11 installed by default on their machines.

  This required installing python 3.10 and dealing with virtual envs.

  With Torch >= 2.0.1 now able to support python 3.11, at least one
  class of installation troubles for Khoj should drop. See
  https://github.com/pytorch/pytorch/issues/86566 for reference

- Preliminary testing indicates using the new torch 2.x may reduce
  search time by 25% (from 80ms to 60ms on Mac M1)

- Update Docs to not require mentioning python <=3.10 required
- Update Github test workflow to run khoj tests with python 3.11 too

The Llama_Hub Github plugin is fairly limited.

The Github Rest API is well supported and can easily be extended to
index commit messages, issues, discussions, PRs etc.

1b4d562700 Test Chat Director Capabilities: Answer from notes, chat history etc
- Chat directors are broad agents.
  - Chat directors orchestrate narrow actor agents to synthesize
    final response for the user
  - Agents are Prompts + ML Model

- Test Chat Director Capabilities
  1. [X] Answer from retrieved notes
  2. [X] Answer from chat history
  3. [X] Answer general questions
  4. [X] Carry out multi-turn conversation
  5. [X] Say don't know when answer not in provided context
  6. [X] Answers that require current date awareness
     This test is expected to fail as the chat is not capable of doing
     this without the Search actor. But the test allows assessing chat quality
  7. [X] Date-aware aggregation across multiple different notes
     This test is expected to fail as the chat is not capable of doing
     this without the Search actor. But the test allows assessing chat quality
  8. [X] Ask clarification questions if no unambiguous answer in provided context
  9. [X] Retrieve answer from chat history beyond lookback window
     This test is expected to fail as the chat director is not capable
     of searching chat history yet. But the test allows assessing chat quality
 10. [X] Retrieve context for answer using multiple independent
         searches on knowledge base
     This test is expected to fail as the chat is not capable of doing
     this without the Search actor. But the test allows assessing chat quality

ad1f1cf620 Improve and simplify Khoj Chat using ChatGPT
- Set context by either including last 2 chat messages from active
  session or past 2 conversation summaries from conversation logs

- Set personality in system message
- Place personality system message before last completed back & forth
  This may stop ChatGPT forgetting its personality as conversation progresses given:
  - The conditioning based on system role messages is light
  - If system message is too far back in conversation history, the
    model may forget its personality conditioning
  - If system message at end of conversation, the model can think its
    the start of a new conversation
  - Inserting the system message before last completed back & forth should
    prevent ChatGPT from assuming its the start of a new conversation
    while not losing personality conditioning from the system message

- Simplfy the Khoj Chat API to for now just answer from users notes
  instead of trying to infer other potential interaction types.
  - This is the default expected behavior from the feature anyway
  - Use the compiled text of the top 2 search results for context

- Benefits of using ChatGPT
  - Better model
  - 1/10th the price
  - No hand rolled prompt required to make GPT provide more chatty,
    assistant type responses
