Adds CLAUDE.md: layout, test commands, the single httpx dependency and the supported Python range. Docs only.
Summary by CodeRabbit
Documentation
Added repository documentation covering setup and testing, supported Python versions, key application areas, implementation conventions, error and polling behavior, and release practices. This provides a consolidated reference for maintaining and validating the project.
Preserves the agent guide drafts written on 2026-09-14 that were left
untracked in the main checkout: commands, CI gate, layout and the
cross-SDK parity rule.
The documentation-only change is low risk, but the guide should be corrected before relying on it for agent work.

Review comments at @CLAUDE.md:
- Line 18: Update the CI description in CLAUDE.md to state that tests run on
Python 3.9 through 3.14 and that pushes to both main and staging trigger CI;
keep the remaining workflow details accurate.
- Line 25: Update the Webclaw description in CLAUDE.md to avoid implying every
method follows a build → request → parse pipeline. State that response-parsing
methods call self._request followed by a parse_* helper, while search,
list_extractors, scrape_vertical, and diff return decoded results directly and
no-content methods discard the result; preserve the shared-helper description.
- Line 32: Update the body-builder guidance in CLAUDE.md to distinguish
endpoint-specific explicit defaults from omission-based defaults, and clarify
that PATCH builders omit fields the caller did not set. Keep the existing
builders—build_crawl_body(), build_batch_body(), and
build_watch_create_body()—unchanged.
- Line 33: Update the parser-safety statement in CLAUDE.md to describe only the
guarantees the code provides: optional fields use defaults, required fields
should use _require(), and nested types use from_dict. Remove claims that nested
lists and objects are always isinstance-guarded or that required fields never
raise a bare KeyError, given the behavior in parse_batch() and
parse_crawl_status().

CI (`.github/workflows/ci.yml`) runs only `pytest`, on Python 3.9 and 3.13, on pushes to `main` and on PRs. No linter, formatter, or type checker is configured. Code must still run on 3.9: every module uses `from __future__ import annotations` so `X | None` hints work there. Don't use runtime-evaluated 3.10+ syntax such as `match` or `|` in `isinstance`.

Three modules split every endpoint, so sync and async can't drift:
- **`webclaw/_endpoints.py`**: all transport-free logic. `build_*_body()` turns kwargs into the JSON body. `parse_*()` turns a response dict into a dataclass. It also holds the route constants and the job-state vocabulary (`SUCCESS_STATE`, `FAILURE_STATES`, `IN_PROGRESS_STATES`).
- **`webclaw/client.py`**: `Webclaw` (sync httpx). Each method is `build → self._request → parse`. It also owns the shared private helpers: `_raise_for_status`, `_decode_json_body`, and the poll-loop pieces.
Limit the request-pipeline sentence to methods that parse responses.
Several Webclaw methods do not call a parse_* helper after self._request. search, list_extractors, scrape_vertical, and diff return the decoded _request result as is. Several no-content methods call _request and return nothing. The sentence "Each method is build → self._request → parse" is therefore inaccurate. Some parsing methods also have no build_* step, so the build part does not apply to every method either.

**Adding or changing an endpoint touches:** a builder and a parser in `_endpoints.py`, the response dataclass in `types.py`, the same method in both clients, exports in `__init__.py` (both the import list and `__all__`), tests for sync (`test_client.py`) and async (`test_async_client.py`), and the README section. The workspace rule is that all three SDKs (`../sdk-js`, `../sdk-go`) expose identical endpoints, and docstrings cross-reference their equivalents.

- **Body builders omit anything left at its default** (`None`, `False`, or the server default). That way the server applies its own default and a PATCH stays partial. Add new optional params the same way. Don't send an explicit `null` or `false`.
Narrow the guide instead of changing these builders. The available source does not establish that omission has the same API behavior for these endpoints.

### Conventions baked into the code
-- **Body builders omit anything left at its default** (`None`, `False`, or the server default). That way the server applies its own default and a PATCH stays partial. Add new optional params the same way. Don't send an explicit `null` or `false`.+- **Body builders omit optional fields when the endpoint uses omission to apply a server default.** Some endpoint builders send explicit endpoint defaults. PATCH builders omit fields that the caller did not set. Don't send an explicit `null` or `false` unless the endpoint requires it.
- **Parsers are tolerant, with one exception.** Optional fields use `.get()` with a default, and nested lists/objects are `isinstance`-guarded. Fields the SDK can't work without go through `_require()`, which raises `WebclawError("Malformed … response")` instead of a bare `KeyError`. Nested types use a `from_dict` static method (lead, watch, X, endpoints).
- **Some endpoints return raw JSON on purpose:** `search` (typed as the `SearchResponse` TypedDict), `diff`, `list_extractors`, `scrape_vertical`.
- **Errors** (`errors.py`): 401/403 → `AuthenticationError` (paid-only X endpoints return 403 too), 404 → `NotFoundError`, 429 → `RateLimitError`, everything else → `WebclawError(status_code=…)`. The error body may be non-JSON or a non-object, and `_raise_for_status` falls back to the raw text. `webclaw.TimeoutError` deliberately shadows the builtin. It covers both httpx request timeouts and poll deadlines. Empty and 204 bodies decode to `None`.

The guide says nested lists and objects are isinstance-guarded, and that required fields never raise a bare KeyError. Two parsers do not follow this:
parse_batch() reads r["url"] directly. A successful batch response with a result that lacks url raises a bare KeyError.
parse_crawl_status() and parse_batch() iterate their page or result lists without an isinstance check. A non-mapping entry can raise TypeError or WebclawError, depending on its type.
Narrow the sentence to the guarantee the code provides:
