feat: v2 SDK rewrite with Pydantic + httpx

[FrancescoSaverioZuppichini]

Summary

Complete SDK rewrite matching the JS SDK 1:1:

• Pydantic v2 for all request/response models with automatic camelCase serialization
• httpx for sync and async HTTP clients
• ApiResult[T] wrapper pattern - no exceptions, just status: "success" | "error"
• Nested resources - sgai.crawl.start(), sgai.monitor.create(), sgai.history.list()
• uv as package manager with modern src/ layout

Changes

• Restructured from nested scrapegraph-py/ to root-level uv library
• All Pydantic models in single schemas.py with CamelModel base class
• Sync client (ScrapeGraphAI) and async client (AsyncScrapeGraphAI)
• 32 examples (16 sync + 16 async) for all endpoints
• 28 unit tests with mocked httpx
• Simplified CI workflows for uv

API Surface

from scrapegraph_py import ScrapeGraphAI, ScrapeRequest

sgai = ScrapeGraphAI()  # reads SGAI_API_KEY from env
result = sgai.scrape(ScrapeRequest(url="https://example.com"))

if result.status == "success":
    print(result.data["results"]["markdown"]["data"])

Test plan

• All 28 unit tests pass (uv run pytest tests/test_client.py -v)
• Integration tests pass with real API key
• Lint passes (uv run ruff check .)
• CI workflow runs successfully

Conflict resolution

Merged origin/main into feat/v2-migration (commit 7eca9cc):

• scrapegraph-py/CHANGELOG.md, scrapegraph-py/pyproject.toml, scrapegraph-py/scrapegraph_py/client.py, scrapegraph-py/scrapegraph_py/async_client.py — accepted the PR's delete. Main only added a v1.12.3 deprecation notice to the old nested package; this PR restructures to a root-level src/ layout, so the old subdir is gone by design.
• package.json — auto-merged (repo URL update from main)

Local validation (all green)

• uv sync ✅
• uv run ruff check src/ tests/ ✅ — all checks passed
• uv run pytest tests/ -v ✅ — 28/28 pass (1 skipped) in 0.34s

Note: uv run ruff check examples/ reports 127 style errors (mostly I001 import sort + E402 because load_dotenv() is intentionally called before imports). Cosmetic, scoped to examples, not blocking.

Live integration tests — ⚠️ 2 bugs found

Ran against https://sgai-api-v2.onrender.com/api/v2 (production api.scrapegraphai.com rejects this key). See the follow-up comment for full details — the short version:

• ✅ credits, health(), scrape (default + fetch_config), extract, search, full crawl lifecycle all pass
• ❌ history.list crashes with a Pydantic validation error — HistoryEntry.result is typed as dict but the API returns null for pending/errored entries. Fix: result: dict | None = None at src/scrapegraph_py/schemas.py:442
• ❌ Method is sgai.health() but JS SDK uses sgai.healthy() — breaks the "1:1 parity" claim in the PR description. Pick one name and align both SDKs.

Live integration results — 2 bugs found ⚠️

Ran against https://sgai-api-v2.onrender.com/api/v2 (staging — production api.scrapegraphai.com rejects this key as invalid).

❌ Bugs

1. history.list crashes on entries with null result

1 validation error for HistoryPage
data.4.result
  Input should be a valid dictionary [type=dict_type, input_value=None, input_type=NoneType]

schemas.py:442 declares result: dict on HistoryEntry, but the API returns null for pending/errored/in-flight entries. Fix: make it optional.

# src/scrapegraph_py/schemas.py:442
result: dict | None = None

2. Method named health(), but JS SDK uses healthy() — breaks 1:1 parity claim

PR description says "SDK matching the JS SDK 1:1". JS exposes sgai.healthy(); Python exposes sgai.health(). Pick one and align both SDKs (the JS PR #13 uses healthy). Affects:

• src/scrapegraph_py/client.py:242
• src/scrapegraph_py/async_client.py (same method)
• Examples under examples/utilities/health*.py

Credits consumed during Python run: ~12 (475 → 463). SDK core works; only the history deserialization is a real functional bug, the health vs healthy is a consistency issue.
