fed-sx-m2: Step 5a — per-actor :actor_inbox log bucket + 14 tests
Adds the receiving-side log bucket every actor needs. add_actor/4
now opens a fresh in-memory log via log:open(ActorId, inbox_base_stub())
and stores it on the bucket as {actor_inbox, LogState} alongside
the outbox {log, _}. Two distinct base stubs ensure the in-memory
log module returns separate states even when the same ActorId is
the actor.

Pure-functional exports:
  actor_inbox_state/2(ActorId, State) -> {ok, LogState} | {error, _}
  actor_inbox_tip/2(ActorId, State) -> integer | nil
  append_to_actor_inbox/3(ActorId, Activity, State)
      -> {ok, NewTip, NewState} | {error, no_actor, State}

gen_server exports (mirror the outbox shape):
  inbox_tip_for/1(ActorId) -> integer | nil
  inbox_state_for/1(ActorId) -> {ok, LogState} | {error, _}
  append_inbox/2(ActorId, Activity) -> {ok, NewTip} | {error, _}

handle_call dispatch added for all three.

Inbox and outbox tips are completely independent — appending to one
doesn't touch the other. This is the storage primitive 5b will
build the inbound validation pipeline on top of.

log:append/2 signature noted in code + progress log: it takes
(LogState, Activity) and returns {ok, NewState, Seq} — not
{ok, NewState} as I originally guessed.

next/tests/inbox_bucket.sh 14/14:
  - fresh inbox tip = 0 (pure)
  - actor_inbox_state {ok, _} (pure)
  - append_to_actor_inbox/3 -> {ok, 1, _}
  - tip advances after append
  - unknown actor -> {error, no_actor, _}
  - outbox + inbox tips fully independent
  - two actors maintain independent inbox state
  - gen_server inbox_tip_for/1 starts at 0
  - gen_server append_inbox/2 -> {ok, 1}
  - gen_server inbox != outbox tip
  - gen_server unknown -> {error, no_actor}
  - gen_server inbox_state_for {ok, _}
  - two appends -> tip = 2

Conformance 761/761. 125/125 across 7 Step-5-adjacent suites
(inbox_bucket, nx_kernel_multi, nx_kernel_server, bootstrap_start,
http_publish, http_multi_actor, actor_lifecycle, smoke_app_pure).
