restructure: reorganize navigation and file system for multi-version support

Refactor docs.json navigation to Languages → Tabs → Versions → Groups
hierarchy per Mintlify design spec. Mirror the structure in the file
system as zh/manual/v1.3.0/ to allow future versions to coexist.
Update all internal cross-references accordingly.
