Function run 

pub fn run(
    all: bool,
    package_names: &[String],
    yes: bool,
    dry_run: bool,
    explain: bool,
    plan_json: bool,
    verbose: bool,
    interactive: bool,
) -> Result<()>

The primary high-level orchestration for the zoi update command.

This function handles:

• Batch Updates: When --all is specified, it scans all installed packages.
• Targeted Updates: Updates specific packages provided by name.
• Advisory Deltas: Calculates and displays changes in security vulnerabilities.
• Cleanup: Automatically removes old versions after a successful upgrade (if rollbacks are not required).

Per-package failures are printed inline as they happen; a single summary with the aggregated counts is printed at the end.

Errors

Returns an error if the package names cannot be expanded.
