The embedding guide (extension mechanism: Credential / Transport /
Restrict / Observer / Wrap / On) lives on the Open Platform doc site,
but the repo itself never mentions it — enterprise IT scanning GitHub
cannot discover the centralized-integration path at all.
- README(.zh): add a 'Personal or Enterprise?' routing table right
after 'Why lark-cli?', linking the official embedding guide and
extension/; add 'Enterprise' to the nav bar; document the '.md'
raw-Markdown trick for AI Agents
- extension/README.md: thin index mapping packages to extension
points, pointing to platform/README.md and the official guide
