SDK regeneration (#66)

* [fern-generated] Update SDK

Generated by Fern
CLI Version: unknown
Generators:
  - fernapi/fern-python-sdk: 5.12.12

* [fern-replay] Applied customizations

Patches applied (1):
  - patch-0c9e9b4e: refactor: rename agent-swarm -> agent-crew across SDK + CLI (4.4.2)

* release: 5.3.1 — billing endpoints, calls timestamp fix, agent-crew deploy DevX

- Bump 5.3.0 -> 5.3.1 + changelog.
- Billing rides the regen: client.atoms.billing (get_balance, get_ledger,
  get_usage_breakdown, list_invoices, get_invoice_pdf) on the payment base.
- calls transcript timestamp now typed as string (ISO-8601), was number.
- agent-crew deploy DevX (cli/, .fernignore'd): pre-deploy layout check
  (src/ layout, nested entry, pyproject-without-requirements) and a corrected
  env-var warning pointing to the .env + load_dotenv path.
- Pass payment= to the four hand-written SmallestAIEnvironment constructions
  (examples + velocity tests) now that the env has a payment url.

Gauntlet on the built wheel: mypy clean, scripts/verify.py PASSED, custom suite
41 passed, fresh-install imports + surface OK (atoms.billing present).

+## 5.3.1 - 2026-07-29
+
+Billing read endpoints, a call-log type fix, and clearer agent-crew deploy warnings. Additive; no breaking changes.
+
+* **Billing** (new `client.atoms.billing`): `get_balance`, `get_ledger`, `get_usage_breakdown`,
+  `list_invoices`, `get_invoice_pdf` (read-only credit and invoice endpoints under `/payment/v1`).
+* **Fix**: `calls.get` / `calls.list` transcript-turn `timestamp` is typed as a string (ISO-8601),
+  matching what the API returns. Previously typed as a number, which triggered a deserialization
+  warning.
+* **CLI DevX** (`smallestai agent-crew deploy`): a pre-deploy layout check warns on a `src/` layout,
+  a nested entry point, or a `pyproject.toml` with no `requirements.txt` (all fail the cloud build);
+  and the environment-variable warning now points to the working path (ship a `.env` at the project
+  root and call `load_dotenv()`; it deploys with your code) instead of just saying it is not propagated.
+
 ## 5.3.0 - 2026-07-28
 
 Unified speech-to-text namespace (breaking), voice cloning, Electron LLM, webhook update.
