Three new tutorial pages:
- Building a REST API: full CRUD with Pydantic validation, from scratch
- Using SQLAlchemy: async engine, lifespan setup, CRUD with ORM
- Migrating from Flask: concept mapping, quick reference table,
gradual migration via app mounting
Also rewritten:
- CLI docs: cleaner, more concise
- API reference: added prose descriptions for each section

Every section now teaches web development concepts alongside the code:
- HTTP methods, status codes, content negotiation explained
- What ASGI is and why it matters
- How cookies, sessions, CORS, and HSTS work
- When to use WebSockets vs SSE
- Why request validation matters
- How background tasks differ from task queues
- What rate limiting protects against
- What Host header injection is
- Separation of concerns in templating
People should learn about web development while reading these docs.

New sections: request validation, headers/cookies, custom error
handlers, before/after hooks, and practical tips. Every section
now explains the why, not just the how.

New features:
- Request ID: api = responder.API(request_id=True)
- Rate limiting: RateLimiter(requests=100, period=60).install(api)
- MessagePack format: await req.media("msgpack")
- All new features documented in tour

Five new features:
1. **Pydantic auto-validation** — if request_model is set, request
bodies are validated automatically and 422 returned on failure.
If response_model is set, resp.media is serialized through the
model (extra fields stripped, types enforced).
2. **Server-Sent Events** — resp.sse for real-time streaming:
@resp.sse
async def stream():
yield {"event": "update", "data": "hello"}
3. **resp.stream_file()** — stream large files without loading
into memory, with automatic content-type detection.
4. **after_request hooks** — run code after every request:
@api.after_request()
def add_request_id(req, resp):
resp.headers["X-Request-ID"] = str(uuid.uuid4())
5. **Route groups** — organize routes with shared prefixes:
v1 = api.group("/v1")
@v1.route("/users")
def list_users(req, resp): ...
Also fix streaming responses not sending Content-Type headers.
172 tests, 95% coverage.

Three approaches: Pydantic models (recommended), YAML docstrings,
and marshmallow schemas — all work together.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Define your API schemas with Pydantic models instead of (or alongside)
YAML docstrings and marshmallow:
from pydantic import BaseModel
class PetIn(BaseModel):
name: str
age: int = 0
class PetOut(BaseModel):
id: int
name: str
age: int
@api.route("/pets", methods=["POST"],
request_model=PetIn, response_model=PetOut)
async def create_pet(req, resp):
data = await req.media()
resp.media = {"id": 1, **data}
Also works with @api.schema("Name") decorator for registering
standalone schema components.
Pydantic models, marshmallow schemas, and YAML docstrings can all
be used together in the same API.
Also: rewrite docs with more prose, restore sidebar logo and links,
add FastAPI acknowledgment, update homepage copy.

Replace all poe task runner usage with direct pytest/sphinx/ruff
commands. Remove poethepoet dependency and [tool.poe.tasks] config.

- Remove commented-out tests (route overlap, form data, file uploads)
- Remove stale TODO/FIXME comments from routes.py and api.py
- Make CLI npm error assertions case-insensitive and more flexible
to handle different npm versions across CI environments

Replace with stdlib urllib.request. No third-party HTTP client
needed for test probing.

All package metadata now lives in pyproject.toml. Removes setup.py
and MANIFEST.in. Also exports __version__ from the package root.
