We have very similar code in corp, moving it to util/precompress allows
it to be reused.

- A network-lock key is generated if it doesn't already exist, and stored in the StateStore. The public component is communicated to control during registration.
- If TKA state exists on the filesystem, a tailnet key authority is initialized (but nothing is done with it for now).

JS -> native nodes worked already, tested by exposing a fetch() method
to JS (it's Promise-based to be consistent with the native fetch() API).
Native nodes -> JS almost worked, we just needed to set the LocalBackend
on the userspace netstack.

Avoids waterfalling of requests from the file (its load is triggered
from JavaScript).
Also has other cleanups to index.html, adding a <title> and moving the
<script> to being loaded sooner (but still not delaying page rendering
by using the defer attribute).

Changes Gzip and Brotli to optimize for speed instead of size. This
signficantly speeds up Brotli, and is useful when iterating locally
or running the build during a CI job (where we just care that it
can successfully build).

Makes the terminal container DOM node as large as the window (except for
the header) via flexbox. The xterm.js terminal is then sized to fit via
xterm-addon-fit. Once we have a computed rows/columns size, and we can
tell the SSH session of the computed size.
Required introducing an IPNSSHSession type to allow the JS to control
the SSH session once opened. That alse allows us to programatically
close it, which we do when the user closes the window with the session
still active.
I initially wanted to open the terminal in a new window instead (so that
it could be resizable independently of the main window), but xterm.js
does not appear to work well in that mode (possibly because it adds an
IntersectionObserver to pause rendering when the window is not visible,
and it ends up doing that when the parent window is hidden -- see
xtermjs/xterm.js@87dca56dee)

The go wasm process exiting is a sign of an unhandled panic. Also
add a explicit recover() call in the notify callback, that's where most
logic bugs are likely to happen (and they may not be fatal).
Also fixes the one panic that was encountered (nill pointer dereference
when generating the JS view of the netmap).

Integrates Tailwind CSS as an esbuild plugin that invokes the CLI
to process the input. It takes ~400ms, so it seems like the easiest
option (vs running a separate process for dev mode).
Existing minimal look and feel is replicated with Tailwind classes,
mostly to prove that the entire system works, including unused
class removal.
Also fixes yarn warnings about package.json not having a license
(which were showing up when invoking any scripts).

This allows gitops-pusher to detect external ACL changes. I'm not
sure what to call this problem, so I've been calling it the "three
version problem" in my notes. The basic problem is that at any given
time we only have two versions of the ACL file at any given point:
the version in CONTROL and the one in the git repo. In order to
check if there has been tampering of the ACL files in the admin
panel, we need to have a _third_ version to compare against.
In this case I am not storing the old ACL entirely (though that could
be a reasonable thing to add in the future), but only its sha256sum.
This allows us to detect if the shasum in control matches the shasum
we expect, and if that expectation fails, then we can react
accordingly.
This will require additional configuration in CI, but I'm sure that
can be done.

Adds a tool/yarn helper script that uses specific versions of yarn and
node, downloading them if necessary.
Modeled after tool/go (and the yarn and node Redo scripts from the
corp repo).
Also allows the path to yarn to be overidden (in case the user does not
want to use this script) and always pipes yarn output (to make debugging
and viewing of process easier).

When using tsconnect as a module in another repo, we cannot write to
the ./dist directory (modules directories are read-only by default -
there is a -modcacherw flag for `go get` but we can't count on it).
We add a -distdir flag that is honored by both the build and serve
commands for where to place output in.
Somewhat tedious because esbuild outputs paths relative to the working
directory, so we need to do some extra munging to make them relative
to the output directory.

Runs a Tailscale client in the browser (via a WebAssembly build of the
wasm package) and allows SSH access to machines. The wasm package exports
a newIPN function, which returns a simple JS object with methods like
start(), login(), logout() and ssh(). The golang.org/x/crypto/ssh
package is used for the SSH client.
Terminal emulation and QR code renedring is done via NPM packages (xterm
and qrcode respectively), thus we also need a JS toolchain that can
install and bundle them. Yarn is used for installation, and esbuild
handles loading them and bundling for production serving.
