feat: derive recommended version from changelog; no version file required

- RecommendedTag now reads the current version from the most recent
  released section heading in the changelog (## [x.y.z] - ...) when no
  --version-file flag is given, removing the dependency on a separate
  version file for recommendation.
- When the changelog contains no prior releases, the base version
  defaults to 0.0.0, so the first recommended tag is v1.0.0 (or higher
  depending on unreleased content).
- Prepare creates the release-version file if it does not already exist,
  so new repositories do not need to pre-seed it.
- Add tests covering changelog-based version resolution, first-release
  default, and automatic file creation.
- Update README and changelog unreleased section to document the new
  behaviour.

By default, `vociferate` reads and writes the release version as the sole content of a root-level `release-version` file. Repositories that keep the version inside source code should pass explicit `version-file` and `version-pattern` values.
When no `--version-file` flag is provided, `vociferate` derives the current version from the most recent released section heading in the changelog (`## [x.y.z] - ...`). If no prior releases exist, it defaults to `0.0.0` and recommends `v1.0.0` as the first tag.
When running `--version`, the `release-version` file is created automatically if it does not exist, so new repositories do not need to pre-seed it.
Repositories that keep the version inside source code should pass explicit `--version-file` and `--version-pattern` values; in that case the version file is used directly instead of the changelog.
