chore(container): bump claude-code 2.1.116 → 2.1.128

12 patch versions ahead. The 2.1.120 binary baseline introduced a
number of plugin and skill behaviors that have since landed in the
public Claude Code docs: ${CLAUDE_EFFORT} substitution, settled
`arguments` field in skill frontmatter, plugin `channels` field.

No breaking changes for nanoclaw's runtime contract. Verified by
running container/skills/{agent-browser,vercel-cli,slack-formatting}
under the bumped image; all three load and execute as expected.
SDK at ^0.2.116 (caret) remains compatible with claude-code 2.1.128.

Bumping CLAUDE_CODE_VERSION invalidates the pnpm install layer in
container/Dockerfile and triggers a full rebuild of the agent image.
