I strongly dislike 3♣ for a number of reasons. The most concerning is when LHO makes a call of some number of hearts. Now partner does not know we have support, and cannot evaluate his hand properly... That means we're going to have to make a very difficult guess later. The next is that you won't be able to get much useful information from partner, and the later 4♠ bid will pre-empt any further slam investigation. 3♥ describes the hand very well, and is the correct bid IMO.
3♣ is forcing here, if you have a weaker hand with clubs, you have to pass and wait for partner to reopen. Sometimes you'll miss partscores, but overall playing 3♣ as forcing makes life MUCH easier when it's important.
As you said in your original post, 4♠ shows a hand that would accept an Invite. If partner had a hand that would have slam opposite a hand better than an invite, they have a lot of bids between 3♥ and 4♠ to show that. Therefore, partner is limited. I don't want to define limited by HCP, since that isn't accurate. Partner is limited in that they thought that opposite most normal (12)13-15 raises, they don't want to be in slam... But opposite a 10-11(12) raise they want to be in game.
If you think about your relative strength compared to what you have shown, and bids available to partner before making a move over a signoff by partner, it will improve your slam bidding a lot. Here you have shown a decent 10 count or better with 3 card or better support... Your hand isn't too much more than that. Yes, it's got quick tricks, but the small doubleton heart, only three trumps, and lack of club interiors makes this hand not worth more than a minimum GF raise, which will be happy to pass partner's 4♠ call.
Yay for the "Ignored Users" feature!
