[IDEA] Support exclusion file filters

[debanjum]

Describe the feature you'd like

Ability to exclude files or folders from being used by Khoj for a specific chat message

Example message: "Where did jeremy grow up? -file:/home/susan/*.md" should result in exclude susan's markdown notes when looking up answers

Khoj currently only supports inclusion file filters like "Where did jeremy grow up? file:/home/jeremy/*.md" only

Hey @debanjum I'd like to work on this issue. If it's still unassigned, could you please assign it to me?

[debanjum]

Hi @ashanviii , that'd be great! Let us know if you need any help with implementing the feature?
Please refer to the docs for contributing and the implementation of exclusion filters for the word filter to get some direction.
And feel free to suggest edits to the documentation and ask for any help if you're stuck

The file needs to be excluded, right. file filter needs to be updated
