If Covid has taught us anything, it's that it's literally impossible to predict any country's Covid-related entry requirements! But if your final destination is Greece, whatever paperwork you need to get into Greece will be verified when you check in in the US, so you will need to have any required test certificates, completed health forms etc. before you get on the TATL leg of the flight. I cannot envisage the situation you describe happening, in which rule changes would be announced and implemented in the few hours you were in the air/in Munich before boarding. Most countries give at least a couple of days' notice if the rules are changing.
You would obviously need to check for yourself whether entering Germany would impact quarantine regulations for you subsequently entering Greece, but again that's impossible to assess until nearer the time. Ditto whether you meet the requirements for entering Germany. There isn't really a way around this unfortunately. This page in English is useful for Germany's immigration info:
https://www.auswaertiges-amt.de/en/coronavirus/2317268 - there will be something similar for Greece if you google it.
As it stands - if it helps at all - you would be able to enter Germany and then Greece without any extra testing or Covid forms to complete.
FWIW, European countries are generally scrapping Covid regulations rather than introducing new ones, so unless there is some new and catastrophic variant identified in the meantime, people who are fully vaccinated should be fine to travel without quarantine or extra testing, particularly between EU member states. I don't know when you were vaccinated/boosted but some countries now only count your last vaccination as valid if it was completed in the last 270 days. Again, you'll need to check the rules for Greece/Germany nearer the time.
Sorry for not being able to give a definitive answer. This thing is a moving target, albeit one which is hopefully slowing down now. At least info is widely available in English.
May in Munich ought to be pleasant, high teens Celsius or low 20s if we're lucky. (For me that's t-shirt weather but it's all about what you're used to!)
