Explain the responsibilities of modules and plugins, service lookup, configuration and lifecycle ownership in four bilingual guides. Provide a complete external plugin example covering its public headers, CMake target, exported entries, application manifest and actual load/update/unload flow.

The branch incorporates accepted main 6b773269b6c761d18e87bd96665780d24e2447ca. Only the original four guide documents differ; their text and twelve bilingual code blocks are unchanged from the reviewed implementation. The newly accepted source layout and architecture archive are preserved.

Validation at 2e3db816cb9af6ea40ff198ccb96bf371d02b201, tree 2244a4c94c27516215f3d815249eced239d72ca5:

• Fresh Release and Debug external plugin/driver builds against the new layout passed actual initialization, five updates, orderly stop and unload; exported entry pairs and compiled inputs match the documented examples. Runtime/SDK build inputs remain unchanged after incorporating the documentation-only main update.
• Current-source 34 CI/README tests and the complete seven-test Nimbus/site checks passed: no Astro diagnostics, 115 HTML pages and 195 internal references verified.
• Format, local example-link checks, source conservation and whitespace checks passed. The final worktree is clean.

Windows/Linux execution of this particular external example was not performed locally. The guides describe current lifecycle limits and do not introduce hot replacement, a general callback-drain guarantee or a shutdown-policy change. Published-head checks and the actual protected merge-queue candidate remain required before squash acceptance.
