Fix redirects: add /en/ prefix to all redirect sources and destinations

[nearestnabors]

Summary

• Added /en/ locale prefix to all redirect sources and destinations
• Removed duplicate redirects and trailing slash redirects that Nextra handles automatically
• Ensures URLs like /en/home/build-tools/create-a-mcp-server redirect properly to /en/guides/create-tools/tool-basics/build-mcp-server

Changes Made

• ✅ 71 total redirects with proper /en/ prefix
• ✅ No duplicate sources - each source path appears only once
• ✅ No circular redirects - verified no redirect loops
• ✅ No self-referential redirects - all destinations are different from sources
• ✅ Clean syntax - proper TypeScript structure and formatting

Testing

• Analyzed all redirects for duplicates and circular references
• Verified proper /en/ locale prefix on all sources and destinations
• Removed unnecessary trailing slash redirects that Nextra handles automatically

Impact

This fixes 404 issues for internationalized URLs that weren't properly redirecting due to missing locale prefixes.

Note

Updates site routing to the new information architecture and localized URLs.

• Adds comprehensive /:locale/* redirects in next.config.ts (home → guides/resources, MCP servers → resources/integrations, reference/path fixes, and framework alias paths)
• Maps legacy toolkit links in toolkits.tsx (/en/mcp-servers/{category}/{tool}) to /en/resources/integrations/{category}/{tool}/reference
• Enhances findToolkitFromPath in toolkit-utils.ts to resolve toolkits from both /resources/integrations/{category}/{tool} and /.../reference
• Updates remark-glossary to skip glossary auto-linking on /resources/integrations/* pages

Passing my review to @sdserranog - I thought the /lang prefixes should be handled already

[sdserranog]

Yeah, the prefix should be added automatically. I think there's no need to add it; I'm curious why we're doing it. Regarding the functions we added to fix the links for integration, we should remove those. I updated the design system links, and we just need to upgrade the design system version to get the correct link.

[nearestnabors]

So I thought the same. But apparently for 301 redirects, they need the whole path. That was why the redirect from the dashboard wasn't working. I think. I'm happy if you want to take this on and test the redirects, @sdserranog. I'm out of steam.

@nearestnabors I can take this one if it's okay for me to do it first thing tomorrow. I need to step up for today.

mapToNewIA regex requires /en/ prefix that may be absent

The mapToNewIA function's regex pattern ^\/en\/mcp-servers\/... requires the input link to start with /en/mcp-servers/. Based on the PR discussion, the design system likely provides relativeDocsLink values without the /en/ locale prefix since "the prefix should be added automatically." If the design system returns paths like /mcp-servers/productivity/gmail, the regex won't match and the original (potentially broken) link will be returned unchanged. The pattern may need to handle links both with and without the locale prefix.
