Command linting appears to break SQL commands.

### Server

gcloud-mcp

### What did you do?

Server: gcloud-mcp
Verson: 0.5.0
Using with: Cursor

Running spanner queries doesn't appear to work. I've tried the following:

```json
{
"args": [
"spanner",
"databases",
"execute-sql",
"my-db",
"--instance=my-instance",
"--project=my-project",
"--format=json",
"--sql=SELECT 1"
]
}
```

Trying different formatting/delimeters didn't work either:
```json
// Wrapping in quotes
[
"--sql=\"SELECT 1\""
]

// Splitting the flag/value
[
"--sql",
"SELECT 1"
]
```

### What did you see happen?

Got a variety of error messages like the following:

```
UnrecognizedArgumentsError: unrecognized arguments: 1
To search the help text of gcloud commands, run:
gcloud help -- SEARCH_TERMS
```

```
STDERR:
ERROR: (gcloud.spanner.databases.execute-sql) INVALID_ARGUMENT: Syntax error: Unexpected string literal
```

```
UnrecognizedArgumentsError: unrecognized arguments:
SELECT
1
To search the help text of gcloud commands, run:
gcloud help -- SEARCH_TERMS
```

From what I could tell debugging, the linting process splits the args on spaces or doubles up the quotes.

### What did you expect to see?

I expected the results of the query.
