Parameters, Env and Working Directory

Named parameters

A bare name is required; name=value sets a default.

## deploy

```meta
params = ["env=staging", "region"]
```

```bash
echo "deploying to $MX_PARAM_ENV / $MX_PARAM_REGION"
```

mq-task deploy -- region=eu           # env falls back to "staging"
mq-task deploy -- prod eu             # positional, in declaration order
mq-task deploy -- env=prod region=eu  # named

Parameters are exposed as MX_PARAM_<NAME>. A required parameter without a value is an error.

Environment and directory

mq-task deploy --env REGION=eu --env DEBUG=1
mq-task deploy --dir ../other-project

Defaults can be declared in meta:

## deploy

```meta
env = ["REGION=staging", "LOG_LEVEL=info"]
dir = "services/api"
```

CLI --env / --dir override the meta defaults for that run.
