.SYNOPSIS
  Локальный релиз: бамп версии → коммит → тег → push → сборка → upload в Gitea release.

.DESCRIPTION
  Один скрипт от и до. Если Gitea Actions не настроено, это рабочая альтернатива.

.PARAMETER Bump
  Какую часть semver инкрементировать: patch (по умолчанию), minor, major.
  Альтернатива — указать -Version явно.

.PARAMETER Version
  Точная версия (напр. "0.3.0"). Если задана, -Bump игнорируется.

.PARAMETER SkipBuild
  Пропустить сборку (если уже собрано вручную, .exe лежит в release/).

.PARAMETER DryRun
  Показать что произойдёт, но ничего не делать.

.EXAMPLE
  pwsh scripts/release.ps1 -Bump minor
  pwsh scripts/release.ps1 -Version 0.3.0
  pwsh scripts/release.ps1 -Bump patch -DryRun

.NOTES
  Требует переменную окружения GITEA_TOKEN с правом write:repository
  (создаётся в Gitea: Settings → Applications → Generate New Token).
