Yeah, Hayward is the "Big Bad" villain.
Nah he is not a hidden-hand. I mean specifically a hidden-hand actively influencing and manipulation the main "actors". See below for more.
Or Wanda, in her grief, just fully tapped into the chaos magic in the universe by accident and is doing all of this on her own like what was shown in the episode.
How did the letter get in her car? Bad editing? Missing scene? Continuity error?
Wanda said she wasn't doing it. She was unaware of how she did it.
So I agree that that big bad could also be another "Wanda persona". Hence the switching accents etc and rehabilitation possibilities.
Alternate self as I mentioned here:

I actually think it is someone else but we will see. More below:
Most likely that was just a vision that Wanda had of her being destined to be a "Scarlet Witch".
Nope it narratively personifies the persona "scarlett witch" as being distinct from Wanda.
"Vision or no" that ^ is nonetheless the narrative effect on audiences.
A witch having some magic book in her basement isn't that out of the ordinary and the fact that the only glimpse we got of it was in Ep 7 as part of the camera panning the witchy basement decor and we haven't seen it since seems to me like concrete proof that it doesn't matter to the story being told on this show.
You missed where her Mom said that Agnes "stole" (something) ...
They showed smouldering energy, they paused on it and coloured its energy the same exact same orange as used by all the Doctor Strange branch magicians and which was shown to be emanating from the books of magic in Wong's library in doctor strange 1.
Yeah, Agatha's mom told her she was messing with dark magic she wasn't supposed to be touching. And the surprise was basically her being a young untrained witch who assumed she was going to die but was so much more powerful than the rest of the coven that she siphoned their magic instead.
You are making a huge assumption that it was some singular source who was controlling what was going on instead of Agatha just using dark magic the same way Wanda is using chaos magic. Like how The Ancient One was using magic from The Dark Dimension but wasn't being controlled/manipulated by Dormammu.
The Mom said she STOLE from them.
"You
stole knowledge above your age and station". In Doctor Strange where was that advanced knowledge stored ...? In books. In Marvel where is that advanced knowledge kept? In books?
She didn't do the siphoning. Look at the scene again. Agnes was NOT in control. Watch the surprise on Agatha's face. Agnes didn't attack anyone but rather was shocked when the power started to fight by by itself. She looked around trying to understand what was going on.
At this point she didn't know what was going on ..
She also said that her and Ralph's anniversary was the date of the Salem Witch Trials in ep. 1.
I.e. She and Ralph made a "deal" aka got hitched" on that day.
If there are still existing witches covens in the MCU it wouldn't be some shocking thing. It also doesn't mean that it has anything to do with the story being told on this show.
Context clue.. From the show and from posts. This is under another-thing section. Separate from what went before it and not a direct reply to anything that you said.
