With v1.0 it would be pretty easy, but v1.1 makes this more difficult
because it doesn't keep dovecot.index up-to-date all the time. Instead
you'd have to read dovecot.index and apply new changes from
dovecot.index.log.

Create a plugin which overrides mail_storage.sync_deinit(). Quota plugin
could be used as an example:
static int quota_mailbox_sync_deinit(struct mailbox_sync_context *ctx,
enum mailbox_status_items status_items,
struct mailbox_status *status_r)
{
struct quota_mailbox *qbox = QUOTA_CONTEXT(ctx->box);
/* just in case sync_notify() wasn't called with uid=0 */
quota_mailbox_sync_finish(qbox);
return qbox->module_ctx.super.sync_deinit(ctx, status_items, status_r);
}
Call super.sync_deinit() with status_items having STATUS_UNREAD.
status_r->unseen then contains the unseen counter.
If you want to avoid useless database updates, you could call
mailbox_get_status() in sync_init() and save the unseen count there, and
then compare in sync_deinit() if it got changed.
