W7e: delete the native unit pipeline (.so compile + dlopen execution)

Browse Source 
Units now run exclusively on wasm; the native generated-C++ -> clang -> .so ->
dlopen path and its request-time fallback are removed.

- Dispatch (linux_fastcgi.cpp): the 4 handle_complete branches + the CLI-socket
  path route every request through wasm (wasm_ready compiles cold/stale on
  demand); a wasm-unavailable unit now yields a clean error page
  (fail_wasm_unavailable / render_request_failure) instead of native execution.
  compiler_invoke / _cli / _websocket / _serve_http deleted.
- compiler.cpp (-1274): removed the native .so compile (COMPILE_SCRIPT),
  load_shared_unit, dlopen/dlsym/dlclose, compiler_load_shared_unit, and the
  SharedUnit .so function-pointer fields (on_setup/on_render/on_component/
  on_websocket/on_cli/on_once/on_init) in types.h/types.cpp. compile_shared_unit
  now builds only the .wasm side-module; the .uce preprocessor/parser front-end
  is kept (it emits the C++ the wasm compile consumes).
- unit_call()/component()/once/init now resolve across units through the wasm
  host component resolver (uce_host_component_resolve) instead of native dlsym;
  configured runtime error pages render through the wasm backend.
- Dropped the WASM_BACKEND_ENABLED feature flag and dead COMPILE_SCRIPT /
  COMPILE_WASM_UNITS config; unit ABI freshness tied to UCE_UNIT_ABI_VERSION;
  guard against serving a stale .wasm for a deleted source; retired the obsolete
  W5 native-vs-wasm toggle script. Docs updated.

Implemented via the pi agent (with 3 delegated sub-reviews); independently
re-verified on the build host: run_cli_tests --include-wasm-kill => 87 passed,
0 failed, 0 skipped.
