/**
 * CLI tool to update version numbers in package.json, src-tauri/Cargo.toml, and src-tauri/tauri.conf.json.
 *
 * Usage:
 *   pnpm release-version <version>
 *
 * <version> can be:
 *   - A full semver version (e.g., 1.2.3, v1.2.3, 1.2.3-beta, v1.2.3+build)
 *   - A tag: "alpha", "beta", "rc", "autobuild", "autobuild-latest", or "deploytest"
 *     - "alpha", "beta", "rc": Appends the tag to the current base version (e.g., 1.2.3-beta)
 *     - "autobuild": Appends a timestamped autobuild tag (e.g., 1.2.3+autobuild.2406101530)
 *     - "autobuild-latest": Appends an autobuild tag with latest Tauri commit (e.g., 1.2.3+autobuild.0614.a1b2c3d)
 *     - "deploytest": Appends a timestamped deploytest tag (e.g., 1.2.3+deploytest.2406101530)
 *
 * Examples:
 *   pnpm release-version 1.2.3
 *   pnpm release-version v1.2.3-beta
 *   pnpm release-version beta
 *   pnpm release-version autobuild
 *   pnpm release-version autobuild-latest
 *   pnpm release-version deploytest
 *
 * The script will:
 *   - Validate and normalize the version argument
 *   - Update the version field in package.json
 *   - Update the version field in src-tauri/Cargo.toml
 *   - Update the version field in src-tauri/tauri.conf.json
 *
 * Errors are logged and the process exits with code 1 on failure.
