Ignore files/folder defined in gitignore

[domokopter]

When selecting the entire project as context, all contents, including directories like build/, are included, unnecessarily consuming a large number of tokens if I forget to exclude them. I propose adding an option to ignore files and folders specified in .gitignore. I think this option should also be enabled by default.

In the settings you can use something like:
"file_scan_exclusions": ["**/lib/*/*/**"]

in the latest version it actually seems to ignore .gitignore files per default
