docs: update path references for module-folder reorganization

Rewrite src/ and tests/ project paths in docs, CLAUDE.md, README.md, and
test-fixture READMEs to the new module-folder layout (Core/Server/Drivers/
Client/Tooling). References to retired v1 projects (Galaxy.Host/Proxy/Shared,
the legacy monolithic test projects) are left untouched.
