fix(tui): avoid double-formatting friendly tool labels

[CNSeniorious000]

Summary

The TUI treated backend-formatted friendly tool labels as raw context and passed them through formatToolCall(...) again, duplicating the displayed action.

Changes

• Keep raw tool context separate from the optional friendly label across live events and resumed history.
• Render friendly labels directly while preserving legacy formatting for custom tools and disabled friendly labels.

Validation

• Targeted tests/test_tui_gateway_server.py (3 passed)
• bunx vitest run src/__tests__/text.test.ts src/__tests__/createGatewayEventHandler.test.ts src/__tests__/messages.test.ts (114 passed)
• bun run typecheck
• ESLint on all modified TUI files
• git diff --check

Fixes #62796

[teknium1]

Thanks for tracing the producer/consumer contract across live events and resumed history. The core fix is needed: current main passes build_tool_label() through context (tui_gateway/server.py:3441-3445, :3595-3607), and Ink wraps that context (ui-tui/src/components/thinking.tsx:840; ui-tui/src/lib/text.ts:198-203).

Problems

• delegate_task now renders as Delegating … (agent/display.py:582), but ToolTrail only detects Delegate Task at ui-tui/src/components/thinking.tsx:889 and :1066. After this PR's label pass-through at :840, delegated subagents no longer attach inline to their tool group and the /agents hint is omitted.

Suggested changes

• Match both Delegate Task and Delegating through one predicate at both call sites, with a focused delegate-label/subagent rendering test.
