Save chat history to Jupyter Lab's root directory (jupyterlab#770)

* save chat history to jupyter lab root dir

The /export command was saving  chat history in the pwd, i.e., the directory from where JupyterLab is launched rather than the JupyterLab root. For JupyterLab sessions, where the root directory is different from the launch directory, users will not be able to see the exported chat history file in JupyterLab. This is now rectified.

* learn arxiv tex files (jupyterlab#742)

* learn arxiv tex files

* Created a new option remote or -r. Example: /learn -r arxiv <arxiv-id>
* Approach: downloads the tar file for the entire paper into downloads_temp. Then, unzips and collects all .tex files in the tar file and concatenates them. Different authors use various approaches. Some have the entire paper in one tex file, whereas others may have separate tex files for each section, so we need to collect all the tex file into a single file and then hand off to the splitter, embedder. After completion, remove the temp directory. Return a properly formatted error if package arxiv needs to be installed.
* Handle two types of errors: (i) package arxiv not installed. (ii) User enters a wrong paper id.

* Distinguish between completion and chat models (jupyterlab#711)

* Distinguish between completion and chat models

* Fix tests

* Shorten the tab name, move settings button

Lint

* Implement the completion model selection in chat UI

* Improve docstring

* Call `_validate_lm_em_id` only once, add typing annotations

* Remove embeddings provider for completions

as the team has no plans to support it :(

* Use type alias to reduce changeset/make review easier

Without this change prettier reformats the plugin with an extra
indentation, which leads to bad changeset display on GitHub.

* Rename `_validate_lm_em_id` to `_validate_model_ids`

* Rename `LLMHandlerMixin` to `CompletionsModelMixin`

and rename the file from `llm_mixin` to `model_mixin` fro consistency.
Of note, the file name does not need `completions_` prefix as the file
is in `completions/` subdirectory.

* Rename "Chat LM" to "LM"; add title attribute; note

using the title attribute because getting the icon to show up nicely
(getting they nice grey color and positioning as it gets in buttons,
compared to just plain black) was not trivial; I think the icon might
be the way to go in the future but I would postpone it to another PR.

That said, I still think it should say "Chat LM" because it has no
effect on magics nor completions.

* Rename heading "Completer model" → "Inline completions model"

* Move `UseSignal` down to `CompleterSettingsButton` implementation

* Rename the label in the select to "Inline completion model"

* Disable selection when completer is not enabled

* Remove use of `UseSignal`, tweak naming of `useState`

from `completerIsEnabled` to `isCompleterEnabled`

* Use mui tooltips

* Fix use of `jai_config_manager`

* Fix tests

* Fix `unsupported_slash_commands` default (jupyterlab#768)

* Updates to /export command

(1) Save chat history file to Jupyter root directory, not cwd, in markdown format
(2) Add time stamps to the saved files
(3) Enable the `/export <filename>` option, else use default file name.
(4) Remove code to increment file numbers for multiple chat histories, given that the time stamps are now being used.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Update export function

(1) Use argparse to extract filename if the option is used
(2) Remove the old function to get the chat file name and streamline the code

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Add Titan embedding model v2 (jupyterlab#778)

* Add Titan embeddning model v2

Included the new embedding model, released recently on Amazon Bedrock.

+### Exporting chat history
+Use the `/export` command to export the chat history from the current session to a markdown file named `chat_history-YYYY-MM-DD-HH-mm.md`. Using `/export <file_name>` will export the chat history to `<file_name>-YYYY-MM-DD-HH-mm.md` instead. You can export chat history as many times as you like in a single session. Each successive export will include the entire chat history up to that point in the session.

 ### Additional chat commands
 
 To clear the chat panel, use the `/clear` command. This does not reset the AI model; the model may still remember previous messages that you sent it, and it may use them to inform its responses.
