Add bridged chats

doc(config): improve DisableNatPortMap documentation

plugins: support Close() for Tracer plugins as well

fix: make collect-profiles.sh work on mac

With an empty API headers config like

```js
	"API": {
		"HTTPHeaders": {}
	},
```

running collect-profiles.sh shows connection errors when trying to POST to `/debug/pprof-mutex/` end point when using `localhost`.

The same errors do not occur when using `127.0.0.1`

The version of `date` that ships with darwin does not support the `-Iseconds` flag.

Use a pattern with `date` to achieve the same thing but should have better cross platform support.

Most of the tracers available need to properly close to send
the remaining traces before the process exit.

namesys(test): test TTL on publish

These _are_ added/removed from the config.

build: fix golangci again

The patches that required the replace directives have been merged upstream.
Unfortunately, those branches have now been deleted, breaking the build.

GAH!

make: move all test deps to a separate module

1. This means those deps don't get pulled in unless we actually need to test.
2. It means we can cordon all the golangci-lint module replace hacks off into a
   separate package.

fix: close peerstore on stop

feat: web ui 2.5.1

docs: add multiple gateway and api addrs

fixes #6627
