JSON output isn't implemented yet

Error message

JSON output isn't implemented yet

What it means

The `exclude query` command checks which paths are excluded/ignored, but only the human output format is implemented. Requesting JSON output throws this error because JSON serialization of exclude query results does not exist yet.

Solutions

1. Use the default human format (omit the format flag or pass `human`)
2. Parse the human output if automation is required (fragile)
3. Implement or request JSON support for the exclude subcommand

Example fix

// before
exclude::query(repo, query::Options { format: OutputFormat::Json, .. })?;
// after
exclude::query(repo, query::Options { format: OutputFormat::Human, .. })?;

if format != OutputFormat::Human {
    eprintln!("exclude query only supports human output");
    format = OutputFormat::Human;
}

match exclude::query(repo, options) {
    Err(e) if e.to_string().contains("JSON output") => {
        exclude::query(repo, options_with_human_format)?
    }
    other => other?,
}

When it happens

Trigger: Calling `query` in gitoxide-core/src/repository/exclude.rs with `format != OutputFormat::Human`, e.g. `gix exclude query --format json`.

Common situations: CI or tooling that wants machine-readable ignore-check results; developers copying `--format json` from subcommands that do support it.
