Include untracked files in copilot-chat--git-ls-files

[ajdin84]

I'll preface this by saying that I don't know what the intended behavior for this situation is - the change was useful for my use case, so I would like to merge it in case others would find it useful.

When calling copilot-chat-add-workspace, in the case that the working directory/workspace for that chat instance is a git repo, copilot-chat--git-ls-files is invoked to get the list of files to be added to the context list.

copilot-chat.el/copilot-chat-command.el

Line 876 in 9dd4b0c

(aio-await (copilot-chat--git-ls-files repo-root))))

However, this doesn't include untracked files so I added additional arguments to make sure they get included.

As per the git ls-files --help manpage:

       -c, --cached
           Show all files cached in Git’s index, i.e. all tracked files. (This is the default if no
           -c/-s/-d/-o/-u/-k/-m/--resolve-undo options are specified.)

       -o, --others
           Show other (i.e. untracked) files in the output

       --exclude-standard
           Add the standard Git exclusions: .git/info/exclude, .gitignore in each directory, and the
           user’s global exclusion file.

Pull request overview

This PR enhances copilot-chat--git-ls-files to include untracked files when adding workspace files to a Copilot Chat context. Previously, only tracked files were returned; now both tracked and untracked (but not ignored) files are included.

Changes:

• Updated git ls-files command to include --cached, --others, and --exclude-standard flags to return both tracked and untracked files while respecting gitignore patterns
