chore(deps): bump @extrachill/chat ^0.10.1 -> ^0.11.0

[chubes4]

Summary

This is the dep bump that actually makes #7 work end-to-end.

Context

PR #7 renamed the resolveDiff() helper to resolvePendingAction() and updated it to POST /datamachine/v1/actions/resolve with { action_id, decision } — the DM unified pending-action endpoint. But the chat package at ^0.10.1 only exposed diffId / diff_id from parseCanonicalDiff, never actionId. So the DiffCard's onAccept(id) / onReject(id) callbacks were delivering an empty string to resolvePendingAction, which the /actions/resolve endpoint then rejected with a validation error.

The full fix required @extrachill/chat@0.11.0, which landed:

• chat #21 — parseCanonicalDiff now reads actionId / action_id (prioritized) with fallback to diffId / diff_id. Populates both fields on the returned shape so consumers reading either keep working.
• chat #23 — also recognizes container.preview nesting, which is DM's envelope shape from PendingActionHelper::stage().

With 0.11 in place, DiffCard's accept/reject callbacks deliver the real action id and the round-trip works.

Other 0.11 additions

• chat #22 — forwards onToolCalls + sessionContext from <Chat> to useChat. Not used here, but free.

Validation

• npm install @extrachill/chat@^0.11.0 — resolves to 0.11.0.
• npm run typecheck — clean.
• npm run build — clean.

• Used for: Traced the empty-action_id bug through the consumer → package → DM server chain, drafted the upstream chat fixes to close the gap, cut chat 0.11 (Chris ran the publish), then rolled the bump across all three consumers. This PR completes the end-to-end accept/reject flow kicked off by Fix broken Accept/Reject: call /actions/resolve, not /diff/resolve #7.
