//! POM writer for format-preserving updates.

//! Provides surgical XML replacement without altering formatting,
//! comments, whitespace, or XML structure. Used by the `update` command.

//! - [`properties`] — updates `<properties>` values
//! - [`inline`] — updates `<version>` elements in dependency/plugin blocks
