// handleFleetGet implements the 'get' command to retrieve a fleet entity by ID.
//
// This command fetches detailed information about a specific fleet including its
// configuration, managed entity type, scope, tags, and metadata.
//
// The command:
// 1. Validates flag values (done automatically by framework via YAML rules)
// 2. Calls the New Relic API to retrieve the entity by ID using GetEntity
// 3. Validates that the entity exists and is a fleet
// 4. Filters and returns the fleet details
//
// Parameters:
//   - cmd: The cobra command being executed
//   - args: Command arguments (not used)
//   - flags: Validated flag values from YAML configuration
//
// Returns:
//   - Error if fleet retrieval fails, nil on success
