layout: restructure into src/ tests/ android/ scripts/ tools/
- extension/src/{port,platform,codepage} -> src/; native_render -> src/host
(+ dxt, shaders/); libgr2 -> src/gr2; extension/third_party -> third_party
- extension/tests -> tests/port, libgr2/tests -> tests/gr2
- android-native -> android (build.sh, push-client.sh moved in)
- script -> scripts; tools/40250 -> tools/server; oracle -> tools/granny-oracle;
perf tools -> tools/perf
- all build trees under build/ (native, release, android, port-gate)
- xrender:: CMake aliases -> mt::; port-map ledger impl paths rewritten
No code changes. ctest 15/15, port_gate macos+android PASS, port_map check 0 errors.
