#7884: Docs: fix setup-token anchor text

## Summary - Fix FAQ headings/anchors for “setup-token” (add the missing hyphen) so TOC links resolve correctly. ## Why The FAQ links were pointing to `#how-does-anthropic-setuptoken-auth-work` and `#where-do-i-find-an-anthropic-setuptoken`, but the intended wording uses “setup-token”. The mismatch breaks the anchors. ## Files - docs/help/faq.md - docs/zh-CN/help/faq.md ## Tests Not required (docs-only change). <!-- greptile_comment --> <h2>Greptile Overview</h2> <h3>Greptile Summary</h3> Updates the FAQ table-of-contents links and headings to use consistent “setup-token” wording so generated anchors resolve correctly (English + zh-CN). Note: The PR metadata lists routing changes (`src/routing/resolve-route.ts` and its test), but the referenced head SHA (`6ea95843…`) only changes the two docs files; no routing code is actually part of this changeset. <h3>Confidence Score: 5/5</h3> - This PR is safe to merge; it is a docs-only anchor text fix in the referenced commit. - Diff for the specified head SHA only touches FAQ markdown files, making small, targeted TOC/heading adjustments. No functional code paths are modified in this changeset. - No files require special attention <!-- greptile_other_comments_section --> _{(3/5) Reply to the agent's comments like "Can you suggest a fix for this @greptileai?" or ask follow-up questions!} <!-- /greptile_comment -->
