fix(ai-setting): scope org store subscription to curOrg

[Aias00]

Related issue

Closes #2031

Summary

AISetting read const { curOrg } = useOrgStore();, subscribing to the entire org store. The component re-rendered on every org-store change instead of only when curOrg changed. Changed to a scoped selector: const curOrg = useOrgStore((s) => s.curOrg);. Downstream usage (curOrg?.roleCodes) is unchanged.

Affected surfaces

• Frontend / Web
• Backend / API / Storage
• Database plugin / Driver
• JCEF / Desktop packaging
• CI / Build / Release
• Documentation only

Verification

• Commands and results: npx tsc --noEmit -p chat2db-community-client/tsconfig.json — no errors for AISetting/index.tsx.
• Manual verification: A selector swap; curOrg is a direct field on the org store.
• UI evidence: N/A

Risk and compatibility

• Public API or stored data: N/A.
• Database or driver compatibility: N/A.
• Network, privacy, or security: N/A.
• Community / Local / Pro boundary: N/A.
• Backward compatibility: Strictly fewer re-renders; behavior unchanged.

Reviewer map

• Start here: blocks/Setting/AISetting/index.tsx:24 — const { curOrg } = useOrgStore(); -> const curOrg = useOrgStore((s) => s.curOrg);.
• Failure condition: Component still re-renders on unrelated org-store changes.
• Rollback or disable path: Revert this single commit.

Reviewed the scoped org-store selector. It preserves the value contract and removes unrelated store subscriptions; no blocking issue found.
