Some basic testing

Command shows the inspect subcommand

➜  go run ./cmd/foundryctl/ mechanic --help
Diagnose a running deployment.

Usage:
  foundryctl mechanic [command]

Available Commands:
  inspect     Inspect a named entity within a deployment.

Subcommand shows the potential parameters and formats accepted

➜  go run ./cmd/foundryctl/ mechanic inspect --help
Inspect a named entity within a deployment.

The resource path accepts both slash and positional forms, with an optional
leading casting kind (resolved from the lock file when omitted):

  foundryctl mechanic inspect signoz alert <id>
  foundryctl mechanic inspect signoz/alert/<id>
  foundryctl mechanic inspect installation signoz alert <id>
  foundryctl mechanic inspect telemetrystore table <name>

When the deployment was not provisioned by foundry, supply connection details
via flags (or their environment variables) to override the lock file.

Usage:
  foundryctl mechanic inspect <molding> <entity-kind> <entity-id> [flags]

Flags:
      --clickhouse-dsn string   Override the ClickHouse DSN, user:pass@host:port (default $FOUNDRY_CLICKHOUSE_DSN).
  -h, --help                    help for inspect
      --metastore-dsn string    Override the metastore DSN (default $FOUNDRY_METASTORE_DSN).
      --signoz string           Override the SigNoz API address, host:port (default $FOUNDRY_SIGNOZ).
