* feat: allow DERP headers to be set
* chore: remove custom flag
* Clone DERP header on client create
* Adjust to use interface to cast headers

Prior to this change, DERP traffic would route from `coderd` to the
`CODER_ACCESS_URL` to reach the internal DERP server, which may have
resulted in slower connections due to proxying, or the failure of
web traffic entirely.
If your Coder deployment has a proxy in front of it, your traffic through
web terminals, apps, and port-forwarding is about to get a lot faster!
* feat: automatically use websockets if DERP upgrade is unavailable
This might be our biggest hangup for deployments at the moment...
Load balancers by default do not support the DERP protocol, so many
of our prospects and customers run into failing workspace connections.
This automatically swaps to use WebSockets, and reports the reason to
coderd.
In a future contribution, a warning will appear by the agent if it was
forced to use WebSockets instead of DERP.
* Fix nil pointer type in Tailscale dep
* Fix requested changes
* fix(tailnet): Improve start and close to detect connection races
* fix: Prevent agentConn use before ready via AwaitReachable
* fix(tailnet): Ensure connstats are closed on conn close
* fix(codersdk): Use AwaitReachable in DialWorkspaceAgent
* fix(tailnet): Improve logging via slog.Helper()
If an agent went away and reconnected, the wsconncache connection would
be polluted for about 10m because there would be two peers with the
same IP. The old peer always had priority, which caused the dashboard to
try and always dial the old peer until it was removed.

* Add extio
* feat: Add `vscodeipc` subcommand for VS Code Extension
This enables the VS Code extension to communicate with a Coder client.
The extension will download the slim binary from `/bin/*` for the
respective client architecture and OS, then execute `coder vscodeipc`
for the connecting workspace.
* Add authentication header, improve comments, and add tests for the CLI
* Update cli/vscodeipc_test.go

* fix: Improve tailnet connections by reducing timeouts
This awaits connection ping before running a dial. Before,
we were hitting the TCP retransmission and handshake timeouts,
which could intermittently add 1 or 5 seconds to a connection
being initialized.
* Update Tailscale
This could actually cause connections to intermittently fail too
when a CPU is absolutely pegged. It just so happens that only
our runners have been that slow!
