feat: Woodpecker-Plugin bump (Entwurf)

Setzt Version und Tag für den gepushten Branch wie bump-version, dazu hotfix/* -> beta, Bump nur des auslösenden Commits, [skip ci] im Bump-Commit. Nutzer und Autor oumta-ci, Secret oumta_ci_token (oumta-deploy docs/zugaenge.md). plugins.yaml baut beide Plugins. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

+### bump
+
+Sets the version for the pushed branch in `package.json`, commits it as `update version: vX [skip ci]`, tags it and pushes branch and tag. The tag event then starts the build; `[skip ci]` only suppresses push and pull_request events.
+
+- `main`: release from the commit message (`release/x.y[.z]`, `hotfix/x.y.z`), otherwise a patch bump
+- `release/*`, `hotfix/*`: next `vX.Y.Z-beta.N`
+- any other branch: `vX.Y.Z-dev.<UTC timestamp>`; the release line comes from `release_line`, the newest ancestor `release/*` branch, or `package.json`
+
+Only the commit that triggered the pipeline is bumped; if the branch moved on, the step exits without a bump and the newer pipeline takes over.
+
+Settings:
+
+- `git_token` (required): token with write access to the repo (`oumta_ci_token`)
+- `git_user`: default `oumta-ci`
+- `release_line`: optional, `<major>.<minor>[.<patch>]`
+- `author_name`, `author_email`: default `oumta-ci`, `oumta-ci@noreply.git.uesome.de`
+- `remote`: default `CI_REPO_CLONE_URL`
+

+```yaml
