this is take #2 of this PR https://github.com/tldraw/tldraw/pull/3764
This continues the idea kicked off in
https://github.com/tldraw/tldraw/pull/3684 to explore LOD and takes it
in a different direction.
Several things here to call out:
- our dotcom version would start to use Cloudflare's image transforms
- we don't rewrite non-image assets
- we debounce zooming so that we're not swapping out images while
zooming (it creates jank)
- we load different images based on steps of .25 (maybe we want to make
this more, like 0.33). Feels like 0.5 might be a bit too much but we can
play around with it.
- we take into account network connection speed. if you're on 3g, for
example, we have the size of the image.
- dpr is taken into account - in our case, Cloudflare handles it. But if
it wasn't Cloudflare, we could add it to our width equation.
- we use Cloudflare's `fit=scale-down` setting to never scale _up_ an
image.
- we don't swap the image in until we've finished loading it
programatically (to avoid a blank image while it loads)
TODO
- [x] We need to enable Cloudflare's pricing on image transforms btw
@steveruizok 😉 - this won't work quite yet until we do that.

### Release Notes
- Assets: make option to transform urls dynamically to provide different
sized images on demand.
Previously, we were using touch and mouse events to detect when we were
in coarse/fine pointer mode. The problem with this is that many mobile
devices emulate mouse events for backwards compatibility with websites
not built for touch - so many touch events result in mouse events too.
The solution to this is to use the unified pointer events API, and check
the `pointerType` property to determine the device the user is using.
This diff also contains some changes to make it so that multiplayer
rooms "just work" over the LAN when devloping locally.
### Change Type
- [x] `sdk` — Changes the tldraw SDK
- [x] `bugfix` — Bug fix
### Release Notes
- Fix a bug where coarse-pointer mode would get incorrectly detected on
some touch devices
A few things happening here
- Delete our service worker. Turns out that a couple of years back
browsers decided that a service worker is no longer required for a PWA
so you can just have the manifest and still install on the user's
device.
- Cache tldraw's assets as part of the dotcom vite asset pipeline. This
allows them to participate in the asset coalescing (preserving old
versions of asset files so old clients don't stop working when you
deploy new versions of things, see
https://github.com/tldraw/brivate/pull/3132 for more context).
- Add a new 'imports.vite.js' file to the assets package, because we
import a bunch of json translation files, and vite imports .json files
as parsed json objects instead of string urls, and there's no good way
to tell it not to. Even if there was we wouldn't want to impose that
config on our users. So another way to tell vite to load any asset as a
url string is to append `?url` to the end of the import path. That's
what this file does.

### Change Type
- [x] `minor` — New feature
[^1]: publishes a `patch` release, for devDependencies use `internal`
[^2]: will not publish a new version
### Release Notes

after a deploy
This PR moves the tldraw.com app into the public repo.
### Change Type
- [x] `internal` — Any other changes that don't affect the published
package[^2]
