fix(arcee): disable Trinity tools

CHANGELOG.md

@@ -44,6 +44,7 @@ Docs: https://docs.openclaw.ai
 - Agents/sessions: preserve terminal lifecycle state when final run metadata persists from a stale in-memory snapshot, preventing `main` sessions from staying stuck as running after completed or timed-out turns.
 - Gateway/CLI: make `openclaw gateway start` repair stale managed service definitions that point at old OpenClaw versions, missing binaries, or temporary installer paths before starting.
 - Heartbeat/scheduler: make heartbeat phase scheduling active-hours-aware so the scheduler seeks forward to the first in-window phase slot instead of arming timers for quiet-hours slots and relying solely on the runtime guard. Non-UTC `activeHours.timezone` values (e.g. `Asia/Shanghai`) now correctly influence when the next heartbeat timer fires, avoiding wasted quiet-hours ticks and long dormant gaps after gateway restarts. Fixes #75487. Thanks @amknight.
+- Providers/Arcee AI: mark Trinity Large Thinking as tool-incompatible so main-session runs use the same text-only request shape that made subagent runs recover, avoiding the remaining main-session response-shape mismatch after the #62848 transport failover fix. Fixes #62851 and #62847; carries forward #62848. Thanks @Adam-Researchh.
 - Status: show the `openai-codex` OAuth profile for `openai/gpt-*` sessions running through the native Codex runtime instead of reporting auth as unknown. (#76197) Thanks @mbelinky.
 - Gateway: avoid repeated plugin tool descriptor config hashing so large runtime configs do not block reply startup and trigger reconnect/timeouts. (#75944) Thanks @joshavant.
 - Plugins/externalization: keep diagnostics ClawHub packages and persisted bundled-plugin relocation on npm-first install metadata for launch, and omit Discord from the core package now that its external package is published. Thanks @vincentkoc.
