fix(chatgpt): add Traditional Chinese tool labels so --deep-research and --web-search work on zh-TW UI

[GGGODLIN]

Summary

opencli chatgpt ask --deep-research and --web-search fail on a Traditional Chinese (zh-TW) ChatGPT UI. The tool labels in CHATGPT_TOOL_OPTIONS cover only Simplified Chinese and English.

Root cause

clis/chatgpt/utils.js:

'deep-research': { label: 'Deep Research', labels: ['深度研究', 'Deep Research'] },
'web-search':    { label: 'Web Search',    labels: ['网页搜索', '搜索', 'Web Search', 'Search'] },

The zh-TW UI uses different wording, not the Traditional-character form of those strings:

Tool	Simplified UI	Traditional (zh-TW) UI
Deep Research	深度研究	深入研究
Web Search	网页搜索	網頁搜尋

Character conversion does not close the gap: 深度研究 converted character-by-character is still 深度研究, which never appears in the zh-TW menu. selectChatGPTTool matches menu entries by visible text, so the lookup finds nothing and throws.

Fix

Prepend the Traditional Chinese wording to both label arrays, and cover both in the existing chatgpt current tool detection cases. Data-only change; Simplified and English UIs keep their existing behaviour.

Verification

OPENCLI_CONFIG_DIR=$(mktemp -d) npx vitest run clis/chatgpt/utils.test.js — 121 passed. Filtering to the tool-label cases shows the two new ones running:

✓ detects the visible 深入研究 tool label
✓ detects the visible 深度研究 tool label
✓ detects the visible Deep Research tool label
✓ detects the visible 網頁搜尋 tool label
✓ detects the visible 网页搜索 tool label
✓ detects the visible Web Search tool label
Tests  7 passed | 114 skipped (121)

Behavioural check on a zh-TW Pro account. Before:

$ opencli chatgpt ask "ping" --new --deep-research --wait false
ok: false
error:
  code: COMMAND_EXEC
  message: Could not find the ChatGPT Deep Research tool option.

After:

$ opencli chatgpt ask "ping" --new --deep-research --wait false
- conversationId: <redacted>
  tool: Deep Research
  response: ''

The resulting conversation shows the tool applied — the user turn reads:

深入研究
 ping

Tested against opencli 1.8.7 (npm latest at time of writing) with extension v1.0.24.
