feat(host): registry + in-flight table for {.ffiHost.} ...

First increment of typed host callbacks (roadmap #1): the data-structure
layer, independent of the FFI thread and the macro so it can be unit-tested
in isolation.

- FFIHostRegistry: wire-name -> (host fn ptr, userData). A missing entry is a
  normal outcome (the imported proc errors), never a crash — never-crash
  policy. nil fn unregisters.
- FFIPendingTable: monotonic token -> the chronos Future an awaiting
  {.ffiHost.} proc is blocked on. completePending drops unknown/double
  completions; failAllPending errors every outstanding future on teardown so
  no awaiting handler is abandoned.

Both lock-guarded so a host thread and the FFI thread can touch them
concurrently; futures are only ever completed on the FFI thread. 6 unit tests
pass under orc and refc.
