This PR makes a small improvement to the hand tool to address a "long
press"-related issues.

This PR improves a bunch of places where we do "minimum distance
checks". Previously, we were using `Vec.Dist`, which uses `Math.hypot`
to find the actual distance, but we can just as well use the squared
distance. So this PR makes a small improvement to `Vec.Dist2` and then
switches to that method when checking minimum distances.

This PR changes the way `Store.squashHistoryEntries` works. Previously,
the function would iterate through every entry and squash it against the
current entry (using `squashRecordDiffs`) to get the new current entry.
However, `squashRecordDiffs` does basically the same pattern, iterating
through the properties of every diff. As a result, each diff would be
iterated through twice: once as itself, and once again in the next
current.
This PR tweaks the function to operate on as many diffs as possible at
once.

### Release Notes
- Minor improvement when modifying multiple shapes at once.
Currently, we only use native `structuredClone` in the browser, falling
back to `JSON.parse(JSON.stringify(...))` elsewhere, despite Node
supporting `structuredClone` [since
v17](https://developer.mozilla.org/en-US/docs/Web/API/structuredClone)
and Cloudflare Workers supporting it [since
2022](https://blog.cloudflare.com/standards-compliant-workers-api/).
This PR adjusts our shim to use the native `structuredClone` on all
platforms, if available.
Additionally, `jsdom` doesn't implement `structuredClone`, a bug [open
since 2022](https://github.com/jsdom/jsdom/issues/3363). This PR patches
`jsdom` environment in all packages/apps that use it for tests.
Also includes a driveby removal of `deepCopy`, a function that is
strictly inferior to `structuredClone`.

### Test Plan
1. A smoke test would be enough
- [ ] Unit Tests

This PR does a few things to help with performance:
1. Instead of doing changes on raf we now do them 60 times per second.
This limits the number of updates on high refresh rate screens like the
iPad. With the current code this only applied to the history updates (so
when you subscribed to the updates), but the next point takes this a bit
futher.
2. We now trigger react updates 60 times per second. This is a change in
`useValue` and `useStateTracking` hooks.
3. We now throttle the inputs (like the `pointerMove`) in state nodes.
This means we batch multiple inputs and only apply them at most 60 times
per second.
We had to adjust our own tests to pass after this change so I marked
this as major as it might require the users of the library to do the
same.
Few observations:
- The browser calls the raf callbacks when it can. If it gets
overwhelmed it will call them further and further apart. As things call
down it will start calling them more frequently again. You can clearly
see this in the drawing example. When fps gets to a certain level we
start to get fewer updates, then fps can recover a bit. This makes the
experience quite janky. The updates can be kinda ok one second (dropping
frames, but consistently) and then they can completely stop and you have
to let go of the mouse to make them happen again. With the new logic it
seems everything is a lot more consistent.
- We might look into variable refresh rates to prevent this overtaxing
of the browser. Like when we see that the times between our updates are
getting higher we could make the updates less frequent. If we then see
that they are happening more often we could ramp them back up. I had an
[experiment for this
here](4834863966 (diff-318e71563d7c47173f89ec084ca44417cf70fc72faac85b96f48b856a8aec466L30-L35)).
Few tests below. Used 6x slowdown for these.

Comparison is not 100% fair, we don't store the intermediate inputs
right now. That said, tick should still only produce once update so I do
think we can get a sense of the differences.

This PR bumps TypeScript to 5.3.3 and API extractor. We started getting
some weird behavior in CI due to different versions of the two
libraries, ie where the CI api.jsons would differ from those built
locally.

Closes#2800
This PR makes it so that `check-scripts` will error out if you forget to
add a "references" entry to a tsconfig file when adding an internal
dependency in our monorepo.
If these project references are missed it can prevent TS from
building/rebuilding things when they need to be built/rebuilt.

This PR adds a validation mode whereby previous known-to-be-valid values
can be used to speed up the validation process itself. At the same time
it enables us to do fine-grained equality checking on records much more
quickly than by using something like lodash isEqual, and using that we
can prevent triggering effects for record updates that don't actually
alter any values in the store.
Here's some preliminary perf testing of average time spent in
`store.put()` during some common interactions
| task | before (ms) | after (ms) |
| ---- | ---- | ---- |
| drawing lines | 0.0403 | 0.0214 |
| drawing boxes | 0.0408 | 0.0348 |
| translating lines | 0.0352 | 0.0042 |
| translating boxes | 0.0051 | 0.0032 |
| rotating lines | 0.0312 | 0.0065 |
| rotating boxes | 0.0053 | 0.0035 |
| brush selecting boxes | 0.0200 | 0.0232 |
| traversal with shapes | 0.0130 | 0.0108 |
| traversal without shapes | 0.0201 | 0.0173 |
**traversal** means moving the camera and pointer around the canvas
#### Discussion
At the scale of hundredths of a millisecond these .put operations are so
fast that even if they became literally instantaneous the change would
not be human perceptible. That said, there is an overall marked
improvement here. Especially for dealing with draw shapes.
These figures are also mostly in line with expectations, aside from a
couple of things:
- I don't understand why the `brush selecting boxes` task got slower
after the change.
- I don't understand why the `traversal` tasks are slower than the
`translating boxes` task, both before and after. I would expect that
.putting shape records would be much slower than .putting pointer/camera
records (since the latter have fewer and simpler properties)

Biome as it is now didn't work out for us 😢
Summary for posterity:
* it IS much, much faster, fast enough to skip any sort of caching
* we couldn't fully replace Prettier just yet. We use Prettier
programmatically to format code in docs, and Biome's JS interface is
officially alpha and [had legacy peer deps
set](https://github.com/biomejs/biome/pull/1756) (which would fail our
CI build as we don't allow installation warnings)
* ternary formatting differs from Prettier, leading to a large diff
https://github.com/biomejs/biome/issues/1661
* import sorting differs from Prettier's
`prettier-plugin-organize-imports`, making the diff even bigger
* the deal breaker is a multi-second delay on saving large files (for us
it's
[Editor.ts](https://github.com/tldraw/tldraw/blob/main/packages/editor/src/lib/editor/Editor.ts))
in VSCode when import sorting is enabled. There is a seemingly relevant
Biome issue where I posted a small summary of our findings:
https://github.com/biomejs/biome/issues/1569#issuecomment-1930411623
Further actions:
* reevaluate in a few months as Biome matures

Biome seems to be MUCH faster than Prettier. Unfortunately, it
introduces some formatting changes around the ternary operator, so we
have to update files in the repo. To make revert easier if we need it,
the change is split into two PRs. This PR introduces a Biome CI check
and reformats all files accordingly.
## Change Type

This PR adds the docs app back into the tldraw monorepo.
## Deploying
We'll want to update our deploy script to update the SOURCE_SHA to the
newest release sha... and then deploy the docs pulling api.json files
from that release. We _could_ update the docs on every push to main, but
we don't have to unless something has changed. Right now there's no
automated deployments from this repo.
## Side effects
To make this one work, I needed to update the lock file. This might be
ok (new year new lock file), and everything builds as expected, though
we may want to spend some time with our scripts to be sure that things
are all good.
I also updated our prettier installation, which decided to add trailing
commas to every generic type. Which is, I suppose, [correct
behavior](https://github.com/prettier/prettier-vscode/issues/955)? But
that caused diffs in every file, which is unfortunate.

This PR updates the licenses across tldraw to a bespoke tldraw license.
The idea here is leverage dual licensing for revenue from companies
using tldraw. The source code and its distributions are provided under a
non-commercial license (tldraw) while we offer to sell / give out an
alternative exclusive-use license for companies who wish to use the
product for commercial purposes.
- [x] Add new license
- [x] Change licenses in package.jsons
- [x] Update READMEs
- [x] Update docs (separate repo PR)

This prevents geometry from being recalculated when dragging shapes
around. It uses an equality check on the shape props to opt out of
recalculations. This still allows bounds to be calculated based on other
reactive values, so if folks really want to use x,y values or opacity or
whatever, they can call editor.getShape(id) when making their
calculation.
