    /// An error report that contains a context, child reports, and attachments.
    ///
    /// [`Report`] is the main type for creating and working with error reports
    /// in this library. It can contain a root context (typically an error),
    /// zero or more child reports, and zero or more attachments.
    ///
    /// # Type Parameters
    ///
    /// [`Report`] has three type parameters that control its behavior:
    ///
    /// - **Context (`C`)**: The type of the root error or context (defaults to
    ///   [`Dynamic`])
    /// - **Ownership (`O`)**: Controls whether the report can be cloned
    ///   - [`Mutable`]: Unique ownership, can modify but cannot clone (default)
    ///   - [`Cloneable`]: Shared ownership via [`Arc`], can clone but cannot
    ///     modify root
    /// - **Thread Safety (`T`)**: Controls whether the report can be sent
    ///   across threads
    ///   - [`SendSync`]: Can be sent across threads (default, requires all data
    ///     is [`Send`]+[`Sync`])
    ///   - [`Local`]: Cannot be sent across threads (allows non-thread-safe
    ///     data)
    ///
    /// # Common Usage
    ///
    /// The easiest way to create a [`Report`] is with the [`report!()`] macro:
    ///
    /// ```
    /// # use rootcause::prelude::*;
    /// let report: Report = report!("file missing");
    /// println!("{report}");
    /// ```
    ///
    /// You can add context and attachments using method chaining:
    ///
    /// ```
    /// # use rootcause::prelude::*;
    /// let report = report!("database query failed")
    ///     .context("failed to fetch user data")
    ///     .attach("user_id: 12345");
    /// println!("{report}");
    /// ```
    ///
    /// [`Arc`]: triomphe::Arc
    /// [`Local`]: crate::markers::Local
    /// [`Mutable`]: crate::markers::Mutable
