fix(bump): Schutz vor Doppel-Tags nur für Tags derselben Art (#5)

Der Schutz „Commit trägt schon ein v-Tag, nichts tun“ zählt jetzt nur Tags derselben Art (dev, beta, stabil). Vorher hätte ein dev-Tag nach einem Fast-Forward-Merge in `release/*` das Beta-Tag und damit Build und Deploy nach beta verhindert.

Getestet im lokalen Harness: Feature vom Release-Head taggen, Fast-Forward nach `release/2.4`, Lauf auf release ergibt `v2.4.1-beta.2` auf demselben Commit; erneuter Lauf tut nichts. Release als `bump-v2.0.1`.

+Plugins are Docker images built from `woodpecker/<name>/` by `.woodpecker/plugins.yaml`. A tag `<name>-vX.Y.Z` publishes `git.uesome.de/actions/ci-cd/<name>:vX.Y.Z`; pipelines pin that version. The push uses `oumta-ci` with the Woodpecker secret `oumta_ci_token`, so `oumta-ci` needs package write access in the org `actions`.
+
+The secret `oumta_ci_token` holds the one token `oumta-ci` writes with. Limit it in Woodpecker to the images `woodpeckerci/plugin-docker-buildx:6`, `git.uesome.de/actions/ci-cd/bump` and `git.uesome.de/actions/ci-cd/deploy` and to the events `push`, `tag` and `manual` (zugaenge.md in oumta-deploy).

 ### 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.
+Derives the next version for the pushed branch and pushes it as a tag on the triggering commit. There is no version commit: the build takes the version from the tag (`CI_COMMIT_TAG`, e.g. as build arg `VERSION: ${CI_COMMIT_TAG##v}`), `package.json` stays untouched. The tag event then starts the build.
 
-- `main`: release from the commit message (`release/x.y[.z]`, `hotfix/x.y.z`), otherwise a patch bump
+- `release/X.Y[.Z]`, `hotfix/X.Y.Z`: next `vX.Y.Z-beta.N` of that line (D8). A hotfix needs a patch number.
-- `release/*`, `hotfix/*`: next `vX.Y.Z-beta.N`
+- `production/*`: no bump, the step fails. A release is a retag of a beta image (D9).
-- any other branch: `vX.Y.Z-dev.<UTC timestamp>`; the release line comes from `release_line`, the newest ancestor `release/*` branch, or `package.json`
+- the branch in `release_branch` (repos without majors, e.g. oumta-keyklo `main`): next stable `vX.Y.Z`, the highest existing patch of the line plus one
+- any other branch: `vX.Y.Z-dev.<UTC timestamp>`; the line comes from `release_line`, the branch name, the nearest `release/*` or `hotfix/*` branch (newest merge base), or `major.minor` from `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.
+If the stable tag of a line exists (`v2.4.0` after the release), the next patch of that line is used (`v2.4.1-beta.0`, `v2.4.1-dev.…`).
+
+Only the commit that triggered the pipeline is tagged; if the branch moved on, the step exits without a tag and the newer pipeline takes over. A commit that already carries a tag of the same kind (dev, beta or stable) is not tagged again, so a re-run does not build twice; a dev tag does not block the beta tag after a fast-forward merge.
 
 Settings:
 
-- `git_token` (required): token with write access to the repo (`oumta_ci_token`)
