Fix: On run choose the next post, not latest

Amazing tool!

Problem: I use it for a week and noticed that when I post 2 or more posts to Mastodon in between script runs it chooses to repost only the latest Mastodon post to X. I want it to post all of them. I am completely fine to post only 1 X post per script run.

Apologies for the many changes, that's my editor formatting the code.

Important part is this:

# Find the next entry to post
    next_entry = None
    if last_post_id is None:
        # First run - post the latest
        next_entry = feed.entries[0]
    else:
        # Find the entry that comes right after last_post_id
        for i, entry in enumerate(feed.entries):
            if entry.id == last_post_id:
                # Found the last posted entry, get the one before it (newer)
                if i > 0:
                    next_entry = feed.entries[i - 1]
                break

Fix: It picks only the next post right after already synced post. Not the latest one. This way, it posts every Mastodon post 1 by 1 on every script run. 1 run = 1 synced post, but the next post, not the latest one.
