fix: create bump commits via GraphQL API so GitHub signs them - #24

The main ruleset requires verified signatures. git commits made on the runner are unsigned, so bump PRs (e.g. #23) were unmergeable. Branch ref and commit now go through the REST/GraphQL API (createCommitOnBranch), which GitHub signs with its web-flow key. Drops gh auth setup-git and all runner-side git write operations.

PR #23 was unmergeable: the main ruleset requires verified signatures, and the bump commit was created by plain
git commiton the runner — unsigned, since runners have no signing key.Changes

API-created commits are signed by GitHub's web-flow key and show Verified, satisfying the ruleset with no key material in CI.gh auth setup-git,git config user.*,checkout -b,commit,push.sedstill edits the local Dockerfile, but only to compute the new contents for the mutation.git push --deleteto the refs API.After merge: close #23, delete its branch, and re-dispatch — the workflow will recreate the bump PR with a verified commit.
