refactor: simplify public API and isolate native extensions

Separate loop/timer and native interoperability APIs from the portable surface header. Unify dispatch, geometry queries, and timer callbacks; keep framebuffer bookkeeping and frame clocks private, and hide implementation symbols.

Update backends, documentation, examples, and API/integration coverage. Verify exports, strict C/C++ installed consumers, and normal plus ASan/UBSan suites.
