wasm runtime: central WS broker, unified handlers, W7d holdouts, membrane completeness

Browse Source 
- WS: a dedicated broker process owns HTTP_PORT + every connection; it forwards
  renders to the worker pool over uce.sock (non-blocking) and applies ws_*
  command batches flushed back at workspace teardown. Removes the now-dead
  per-worker websocket executor (-509 lines).
- Dispatch: unify CLI / WebSocket / serve_http / page render through one
  serve_via_wasm(entry_unit, handler) path; handler string -> __uce_<handler>
  export symbol.
- W7d: rewrite zip.uce to the membrane return-value error contract (no C++
  try/catch), error-reporting.uce to genuine wasm traps instead of throw, and
  sharedunit.uce to unit_info(); empty the native-only token gate.
- Membrane: wire ls / mkdir / file_mtime through new uce_host_file_list /
  uce_host_file_mkdir / uce_host_file_mtime hostcalls (resolve_guest_file gains
  directory support). Fixes /doc/index.uce listing nothing; adds a regression
  assertion that the index enumerates items.
- Docs: add docs/wasm-runtime-architecture.md; record the W7e staged native-
  deletion plan in WASM-PROPOSAL.md.

Verified: scripts/run_cli_tests.sh --include-wasm-kill -> 87 passed, 0 failed.
