fix(tests): use positional arg syntax in browser search tests (#302)

Replace redundant --keyword/--query named flags with positional
arg syntax for all search commands that declare positional: true.
Also fix --query usage in tiktok.md docs example.

Affected:
- bilibili, weibo, zhihu, reuters, youtube, smzdm, boss, coupang, xiaohongshu search (browser-public.test.ts)
- linux-do search (browser-auth.test.ts)
- tiktok search (docs/adapters/browser/tiktok.md)
