This is full of spoilers, obviously.
Here are some observations on the challenge:
You're going to take the Joja route. To get Full Shipment in Year One is almost impossible if you take the CC route, because you need at least a month on Ginger Island; you need to get the Mango and Banana Saplings and then wait a season for them to mature. Unless you luck into an early Nautilus Shell, Y1/FS is not possible using the CC route. (It used to be, but not post 1.5.)
My Spring was comparable to any other run: Parsnip 1st -> Kale 5th -> Strawberries ramp, fishing for money and mining for metals. I was able to buy 150 Strawberry Seeds on the 13th, which is important because this run requires early money. I fished heavily (figuring it better to be short on metals than money come Sp 13) in the Mountain Lake and it seems to have paid off. It turns out watering (Energy) isn't a problem if you have the Mushroom Cave; it's the energy cost (not time) of watering ~100 Strawberries, if you don't have the Cave yet, that kils you.
On Summer 1, I bought 550 Blueberries and continued fishing for intermediate income. I did the usual rush to Foraging Lv 6 by Summer 12 (to plant Lightning Rods before Summer 13) but that was unnecessary because I ended up never really needing Batteries--this is a one-year run and I simply never got to the point where I needed Iridium Sprinklers. I didn't actually unlock the Desert till Summer 15; I didn't need it.
Summer is when I started making mistakes, because the run diverged from the usual routes in a big way. I paid my Joja fares, but I overinvested in the animal/building ramp early, thinking, e.g., I'd have a harder time getting the Duck Feather than I actually did (in fact, I had it by early Fall). Though, I didn't worry about the Rabbit's Foot (or Deluxe Coop) because I got it from an early Serpent kill. Anyway, I got to Ginger Island for the first time on Summer 24. Not bad for a first swing, but I'm sure it can be improved a lot.
Since I went into the Volcano much earlier than on most runs, I actually bought the Lava Katana. Usually, I wouldn't; the Obsidian Sword is enough for Skull Cavern, and it soon becomes obsolete due to the Galaxy Sword. However, since this run involved early Volcano time, I bought it and got good use from it.
Knowing trees inflexibly require 28 days to mature, I rushed Dragon's Teeth and Mussels. Mussel Nodes don't spawn that often (1-2/day) so it took a while. I didn't have my complete set until Fall 7, making Winter 7 the earliest I could complete the challenge.
In Fall, I grew 1,000 pumpkins (2x500) and pickled them; I ended up having about 600 left over, because it turns out you don't need much money in the second half of this challenge; you're basically going after Ginger Island.
The Cart was kind to me. I got Garlic, the Red Cabbage, and the Articoke early on. I caught a Sturgeon (for Caviar) in summer but then got Caviar from the cart and just built a Carp pond for regular Aged Roe.
Golden Walnuts are where I made some serious mistakes. You need 101 to unlock Qi's Room and make Radioactive Ore/Bars available. There are 130, but quite a few come late from the perspective of a 1-Year challenge. The 5 for the Pirate's Wife are out completely (dependency on Kent) and the 11 for the fossilized animals are hit-or-miss; trying to force them will take up time you don't have. Then there are 3 for the Banana Shrine, and 5 that depend on Garlic. So that's 24 you can't count on. Mussel Nodes (5) are also slow to spawn, so you'll be waiting a while if you depend on them. Therefore, you should plan on hitting the others as soon as possible. Which brings me to...
Mistake 1: I befriended Robin too late. For this run, I focused on shipping at the expense of all else. I didn't go after difficult fish or artifacts, and while I knew I had to get Caroline to 2 hearts, I ignored relationships and forgot about Robin. Whoops. You need her to 6 (!) Hearts to get the Flute Block recipe, which is prerequsite to the Mermaid Quest (5 walnuts). Luckily, I figured that out before Fall 21 (her birthday). Otherwise, it might have killed the run.
Mistake 2: When I got Garlic from the Traveling Cart, I shipped it immediately. I know better; I have no excuse for this. I should have used a Seed Maker to duplicate it, saving 5 Walnuts and getting Qi's Room quicker.
I used a Rain Totem on Ginger Island on Fall 22 to force rain on Fall 23, getting the last walnuts and accessing Qi's Room. I got the Ostrich Egg (10th Journal Scrap) on Fall 25, a then a Dinosaur Egg for Dinosaur Mayonnaise on Fall 26. I got all the Winter stuff on Winter 1, so I just had to wait on the trees (to Winter 7). This got 143/145 shipped items.
And then... I had to wait. I slept from Winter 8 to Winter 21. On Winter 22, I drew the quest Danger in the Deep; I finished on Winter 25 when I finally got a Radioactive Ore (x10). Total calendar time was 109 days, but total active time (I played as if Winter 8-21 had been skipped, i.e. threw away everything produced in that interval) was 95 days.
This challege has two ugly RNG dependencies. The first is Garlic. Check your Cart fare on Stardew Predictor and if you don't see Garlic or a Garlic Seed, start another file (or just cheat it in, [476]). Garlic Seeds will not become available from Pierre even if you have Pierre's Missing Stocklist (I checked) and you also can't use the Deconstructor to suck it out of Oil of Garlic (though you should be able to).
The second RNG dependency is Radioactive Ore. You can get the Bar from the Deconstructor for an all in-cost of 30 Qi Gems (easily achievable) but the only item that deconstructs to Ore is Hyper Speed Grow, which can only be produced if you have the Ore. (There's no way to turn a Radioactive Bar back into 5 Radioactive Ore, or even 1.) So you're screwed unless you get one of the two Qi quests that lets you mine it. Danger in the Deep is better because it unlocks Dangerous Mines, which is available forever, insulating you against a week of lousy luck (it happens sometimes). Radioactive Ore seems to be nonexistent on neutral or bad luck days; note that you probably won't have the charm you get from the truck driver, since it's a one-year run.
This could easily have been done in 92 days with better RNG; 85 (Winter 1) is certainly possible on a more aggressive route. If you never sell Mussels and get to Ginger Island by Summer 13 (eleven days before I did) you'll likely have the resources necessary for the Island Trader to get a complete set of fruit trees by Fall 1. Quicker than 85 is almost impossible; Holly, of all things, becomes the blocker, and while the Cart does sell it, it's one of the rarest Cart items there is (about once every five years).
