azazel_processor: commit 5 — orchestrator state machine (properties 5, 7, 10)

Pass 4 / Finding F, commit 5 of 10 from BUILD_AZAZEL.md. Largest
commit so far; pulls together vidui + shaliach + goral + stages and
adds the state machine + in-flight persistence.

THE STATE MACHINE (six checkpoints, persisted):

  STAGED       → AzazelStaged envelope tagged; payload held by shaliach
  CONFESSED    → vidui carried into the staged value
  ROUTED       → routing committed (always ERETZ_GEZERAH); authorized_by
                 + shaliach attribution recorded
  DESTROYED    → payload references cleared from shaliach;
                 gc.collect() called to release; payload becomes
                 unreachable from any orchestrator-visible code path
  ACKNOWLEDGED → out-of-band ack callback invoked (commit 9 wires
                 Chatzotzrot.signal(:moadim) here)
  RECORDED     → AzazelRecord persisted via callback (commit 7 wires
                 the cross-language L3 file-watcher bridge here)

After RECORDED completes, the in-flight checkpoint file is shredded —
the disposal is now permanent in L3, the in-flight artifact must not
linger.

PROPERTY COVERAGE:

  Property 5 (provisioned infrastructure / sukkot):
    Each checkpoint persists state to <in_flight_dir>/<case_ref>.json
    via write-then-rename (atomic against crash mid-write). list_in_flight
    returns partial disposals so resume tooling can pick them up.
    The Mishkan analog: the sukkot along the wilderness route where
    the ish itti can rest if the disposal halts.

  Property 7 (authorized routing):
    AzazelRecord.authorized_by carries the kohen_gadol identifier;
    AzazelRecord.shaliach carries the ish itti identifier. The
    routing destination is the ERETZ_GEZERAH sentinel (property 12).
    The routing decision is OWNED and traceable; the destination
    is not.

  Property 10 (hard termination):
    The DESTROYED checkpoint clears handler._payload_refs and calls
    gc.collect(). The AzazelRecord contains the vidui — what was
    disposed — but NOT the disposed payload itself. The to_storage_dict
    serialization explicitly excludes payload-shaped fields.

                                           — the single legitimate
                                             entry point; walks the
                                             six checkpoints

  test/test_azazel.py                      21 tests covering:
    HAPPY PATH:
    - dispatch returns AzazelRecord
    - record carries authorization + shaliach attribution
    - record routes to ERETZ_GEZERAH
    - record carries the full vidui

    PROPERTY 10 CI INVARIANTS:
    - record does not carry payload (by attribute name)
    - serialized record does not contain the payload's marker string
    - STRUCTURAL: AzazelRecord dataclass field set has no
      payload-shaped names (catches future regression)
    - STRUCTURAL: no recover/undispose/restore/rehydrate/retrieve
      function in azazel_processor public surface (catches
      future regression)
    - payload references cleared from shaliach at DESTROYED

    PROPERTY 5 CHECKPOINT TESTS:
    - in-flight file shredded after RECORDED
    - checkpoints persist incrementally (verified by inspecting the
      file at ack/rec callback fire-time)
    - list_in_flight returns partial disposals
    - list_in_flight empty when no disposals
    - persistence is atomic (file is valid JSON at every visit)

    ROLE GATE (property 4 still enforced):
    - dispatch refuses inactive handler
    - dispatch refuses non-IshItti

    FILENAME SAFETY:
    - case_ref with slash → ValueError
    - case_ref with NUL → ValueError

    AzazelRecord VALIDATION:
    - authorized_by required
    - shaliach required
    - to_storage_dict omits payload
    - frozen (cannot mutate)

DEFAULTS:

  acknowledger and recorder default to no-op callables. This is
  deliberate for commit 5 — the state machine works end-to-end without
  external side effects, and commits 7 (L3) and 9 (chatzotzrot) plug
  the real handlers into the same callback slots. Tests can supply
  their own to inspect mid-route state.

Tests: azazel_processor 109 passed (was 88, +21). korban_processor
unchanged at 203 passed, 1 skipped. No regressions.

+Azazel orchestrator — the disposal protocol state machine.
+
+Properties 5, 7, 10 of azazel_engineering_reading.md §14.
+
+THE STATE MACHINE (six checkpoints from BUILD_AZAZEL.md):
+
+  STAGED       → input received; AzazelStaged envelope tagged
+  CONFESSED    → vidui constructed (Vayikra 16:21 — kol three times)
+  ROUTED       → destination committed (always ERETZ_GEZERAH);
+                 routing decision recorded with shaliach + kohen_gadol
+                 attribution (property 7)
+  DESTROYED    → payload reference cleared (property 10 — eretz
+                 gezerah, no return)
+  ACKNOWLEDGED → out-of-band ack fired (chatzotzrot signal; commit 9
+                 wires the actual signal — for now invokes a callable
+                 supplied by the caller)
+  RECORDED     → AzazelRecord constructed (commit 7 wires the L3
+                 write — for now invokes a callable supplied by the
+                 caller)
+
+Each checkpoint is a recovery point. If the orchestrator halts
+mid-route (process crash, OS reboot, signal received), in-flight
+disposals can resume from the last completed checkpoint by reading
+the persisted in-flight file.
+
+PROPERTY COVERAGE THIS COMMIT:
+
+  Property 5 (provisioned infrastructure / sukkot):
+    The route is pre-surveyed. Each checkpoint persists state to
+    `<in_flight_dir>/<case_ref>.json` so resume() can pick up
+    where dispatch_for_disposal halted. The Mishkan analog: the
+    sukkot along the wilderness route where the ish itti can rest
+    if the disposal halts mid-route.
+
+  Property 7 (authorized routing):
+    AzazelRecord carries authorized_by (kohen_gadol identifier) and
+    shaliach (ish itti identifier). The routing destination is
+    ERETZ_GEZERAH — opaque (property 12). The decision to route IS
+    owned and traceable; the destination is not.
+
+  Property 10 (hard termination):
+    The DESTROYED checkpoint clears the payload reference from the
+    shaliach (handler.tevilah() releases all held_payload refs).
+    The AzazelRecord contains the vidui — what was disposed — but
+    NOT the disposed payload itself. There is no recover_disposed()
+    function and there must never be one.
+
+LATER COMMITS:
+
+  Commit 6 — adds the protocol envelope (is_yom_kippur_protocol_active,
+             has_explicit_disposal_authorization). Until commit 6,
+             dispatch_for_disposal can be invoked freely — protocol
+             restriction is the gate that wraps it later.
+
+  Commit 7 — wires the recorder callable to L3.Store.record_disposal/1
+             via a cross-language file watcher.
+
+  Commit 9 — wires the acknowledger callable to Chatzotzrot.signal(:moadim).
+             Adds the Korban → Azazel intake routing on empty-vital.

+AzazelRecord — the permanent disposal record.

+AzazelRecord is the gravestone.
+
+CRITICAL: this dataclass MUST NOT carry the disposed payload. It
+carries:
+  - the case_ref (an opaque identifier of WHAT was disposed, not the
+    content of what was disposed)
+  - the vidui (the operator's enumerative naming of what was being
+    disposed, in three categories — avonot/peshaim/chatot)
+  - the routing decision (always ERETZ_GEZERAH; the opacity of the
+    destination is property 12)
+  - the goral outcome (LA_AZAZEL; recorded so an auditor can
+    recompute and verify the goral was honest)
+  - the goral_outcome_id (the full SHA-256 digest, so audit can
+    recompute) — when goral was invoked; absent for inputs that
+    classified deterministically (no goral)
+  - the authorized_by (the kohen_gadol identifier — property 7's
+    authorized-routing requirement)
+  - the shaliach (the ish itti identifier — property 4's
+    role-attribution)
+  - the disposed_at timestamp
+
+If a future contributor adds a `payload` field (or any field
+carrying the disposed content), they violate property 10 — and the
+test_azazel.test_no_payload_in_l3_record check fires. The L3 azazel
