Add a setting to include .gitignore files

[cyber-sra]

Feature description | 功能描述

With different project sturctured the worktree copy patterns are not sufficient (or very tedious to maintain).
Ideally there will be a setting that automatically copies over all .gitignored files (but still respsects the worktree copy ignores).

By default this is not enabled, but can be enabled in the options

@cyber-sra Thanks for the suggestion.

I think this is better handled with workspace-specific settings (.vscode/settings.json). Since each worktree is an independent workspace, you can use different settings for different projects.

Parsing .gitignore doesn't seem appropriate, as it's meant for Git rather than editor behavior, so I don't plan to support it for now.
