feature: quarto use brand

[gordonwoodhull]

Slightly different pattern from other commands:

• --dry-run: show every operation that would happen (overwrite, copy, remove)
• --force: skip and confirm all prompts

--no-prompt was too ambiguous because quarto use template does not allow actions; --force is really clear.

In addition to copying and overwriting, the commands will also remove any extra files that were already in the _brand/ folder. This also invokes a prompt listing those files; saying no to removal does not cancel the rest of the command.

--dry-run and --force also report/force potential removals.

Note: I'm breaking with tradition by introducing new commands under

## Commands

in the changelog. Previously we only put updates to commands here, but I think new commands should be at least as prominent as changes to commands and not buried.

This is partly because I didn't want to hide quarto use brand and partly because I didn't know where else to put it.

I also reordered sections to be more consistent with previous changelogs.

Glad to discuss and rearrange.

I'm going ahead and releasing this.

quarto use brand on christmas day, why not.

Share the brands, share the cheer!
