docs: describe current state only, and fill in the stub READMEs

Drop the history and roadmap asides: which services predate the collection's
conventions, the unwired Open Web UI plan, the generic clone-and-troubleshoot
boilerplate. Services that publish ports or set `restart:` now simply say so.

couchbase, openvpn-as and traffmonetizer had two-line READMEs; give them the
ports, variables and storage the root README promises. traffmonetizer reads
${TOKEN} and had no .env.example, so add one.

# netdata-docker-compose
# netdata
Docker Compose setup to run the [Netdata](https://www.netdata.cloud) monitoring agent.
[Netdata](https://www.netdata.cloud) monitoring agent.
## Quick start
Uses `docker-compose.yml`, and sets `restart: unless-stopped` and
`container_name: netdata` — unlike the platform-managed services described in
the [root README](../README.md).
```bash
docker compose up -d
Runs with `network_mode: host` and `pid: host`, plus `SYS_PTRACE`/`SYS_ADMIN`
and an unconfined AppArmor profile, so it can read host processes and metrics.
The dashboard is therefore on the host's own `19999`, not a published port.
## Environment
| Variable | Purpose |
| --- | --- |
| `NETDATA_CLAIM_TOKEN` | Netdata Cloud claim token. Without it the agent runs standalone. |
```sh
NETDATA_CLAIM_TOKEN=<token> docker compose up -d
```
Access the dashboard at `http://localhost:19999`.
## Storage
## Customization
| Volume | Mount | Holds |
| --- | --- | --- |
| `netdataconfig` | `/etc/netdata` | Agent configuration |
| `netdatalib` | `/var/lib/netdata` | Metrics database, claim state |
| `netdatacache` | `/var/cache/netdata` | Cache |
Set your Netdata Cloud claim token to link the agent to your cloud account:
```bash
NETDATA_CLAIM_TOKEN=your-token docker compose up -d
```
Key defaults you may want to override in `docker-compose.yml`:
| Setting | Default | Notes |
|---------|---------|-------|
| Dashboard port | `19999` | Map to a different host port if needed |
| Volumes | `/proc`, `/sys`, host root | Required for full host metrics |
Host paths (`/`, `/proc`, `/sys`, `/var/log`, the Docker socket, dbus) are
mounted read-only for collection.
