chore: update compatible dependencies

[poe-code-agent]

Summary

• Updated npm lockfile dependencies to the latest versions allowed by current compatible ranges.
• Kept @opencode-ai/plugin on the latest 1.15 patch line for opencode-poe-auth to avoid the Node 22+ engine requirement introduced through the 1.16 dependency chain.
• Refreshed the runtime help snapshot that was stale after validation.

Validation

• npm run build
• npm run lint
• npm test
• npm audit --omit=optional

Constrain the published plugin peer range

This only pins the workspace dev/test copy of @opencode-ai/plugin; it is not installed for consumers of the published package, while the peer range above still accepts *. In an OpenCode 1.16+ project, or when npm resolves the missing peer during npm install opencode-poe-auth, the package can still be paired with the Node-22-only dependency chain this change is trying to avoid. If 1.16 is incompatible with the supported Node 20 path, the peer range needs the same upper bound or the peer should be made optional/non-resolving.
