The alias existed so API payloads could mirror the params key used by
queries defined in datasette.yaml, but it was undocumented and untested,
and the create endpoint is not part of the stable API. The API now only
accepts parameters - sending params is a 400 Invalid keys error. The
documented params key for queries in configuration is unchanged.

Documents the canonical error format, the ok/envelope changes, the
array-to-object endpoint conversions, 401s for invalid tokens, the
pagination and page-size unification, removed legacy keys and formats,
and the new Response.error(), TokenInvalid, count_truncated and
unstable-marker APIs.

next_url became a default table JSON key alongside next, making the
extra a no-op. Requesting ?_extra=next_url now returns the standard
unknown-extra 400 error.

Response.error(messages, status=400) builds a JSON error response in
Datasette's standard error format, alongside Response.json/html/text.
messages can be a single string or a list. All internal error response
construction now uses it - the private views.base._error() helper is
gone and the verbose Response.json(error_body(...), status=...) sites
are converted. error_body() remains for the cases that merge the error
keys into a larger payload (the JSON renderer, handle_exception and the
permission debug payload builders).
Since Response is public plugin API, plugins that build JSON endpoints
now have an obvious way to return errors in the canonical shape.
Documented in the internals documentation, including the guidance to
raise Forbidden/NotFound/BadRequest/DatasetteError instead when the
error should content-negotiate.

The insert, upsert, alter and set-column-type endpoints previously
required Content-Type: application/json while /-/create parsed the body
blind - and insert returned a 500 AttributeError when the header was
missing entirely. The lenient rule is now uniform: the body is always
parsed as JSON and invalid JSON is a 400. This makes curl -d and
requests data=json.dumps(...) invocations work without remembering the
header. Cross-site request forgery remains prevented by the Origin and
Sec-Fetch-Site checks in CrossOriginProtectionMiddleware, which is the
defense the strict content-type requirement was historically standing
in for.

/-/config redacts values for keys whose names contain secret, key,
password, token, hash or dsn. Plugins that follow that naming get
automatic redaction; plugins that don't will leak their secrets on
that endpoint.

An upsert may update existing rows without creating anything, so it
deliberately does not claim resource creation with a 201.

The stored query lists silently clamped out-of-range ?_size= values
(a request for 5000 quietly returned 1000) and did not accept the max
keyword. They now share the table view semantics via a new
parse_size_limit() helper: blank means default, "max" means the
maximum (max_returned_rows for query lists), negative or non-integer
values are a 400, and values over the maximum are a 400 instead of
being silently clamped.
The /-/allowed and /-/rules debug endpoints renamed their bare
page/page_size parameters to _page/_size, matching the underscore
grammar used by every other system parameter, with the same validation
(400 instead of silently capping page_size at 200). Their HTML debug
pages and next_url/previous_url builders use the new names.

docs/json_api.rst now opens with an API stability section declaring
what the 1.x promise covers: documented endpoints, parameters and
response keys are stable with additive-only changes; pagination tokens
are opaque strings; the error format and token restriction semantics
are stable. It lists the exempt tiers: endpoints carrying the
"unstable" marker key, debug and support endpoints (/-/threads,
/-/actions, /-/jump, the permission debug endpoints, table
autocomplete), and keys explicitly labeled unstable such as the
execute-write analysis block. Cross-referenced from the introspection
and permission-debug documentation.

Table JSON responses previously only included the next pagination token
by default - the ready-to-follow next_url required ?_extra=next_url.
Both keys are now always present (null on the final page), which the
pagination documentation already claimed. The next_url extra remains
valid for backwards compatibility.

Unknown ?_extra= names (including internal HTML-only extras such as
display_rows) were silently ignored, so a typo returned the default
payload with no signal. Table, row and query data formats now return
400 "Unknown _extra: <names>". HTML pages continue to ignore unknown
names.

The count extra is computed with a limit subquery, so a count equal to
count_limit + 1 (default 10001) actually means "at least this many" -
but only the HTML view knew that. A public count_truncated extra now
reports the flag and is implicitly included whenever count is
requested, using the same logic the HTML view already used.

Every stored-query object carried the same list of parameter names
twice, as both "params" and "parameters". Output objects now carry only
"parameters", consistent with /-/query/parameters and the two analyze
endpoints (and distinct from the "params" bound-values dictionary used
by the query extra and /-/execute-write). "params" remains an accepted
input alias for query creation, update and datasette.yaml config.

Invalid dstok_ tokens - bad signature, malformed payload, expired, or
presented while allow_signed_tokens is off - previously degraded the
request to anonymous, so clients saw a 403 permission error or worse,
a 200 with anonymous-visible data. Token handlers can now raise
TokenInvalid for tokens they recognize but reject; Datasette responds
with 401, the canonical JSON error body and a WWW-Authenticate: Bearer
error="invalid_token" header, even when a valid cookie is also present.
Bearer tokens no registered handler recognizes are still ignored, so
authentication plugins with their own token formats keep working.
TokenInvalid is exported from the datasette package for use by plugin
token handlers.

POST to a write canned query previously returned HTTP 200 with
{"ok": false, "message": ...} when the SQL failed to execute, so JSON
clients (and anything that trusts HTTP status) recorded success for
failed writes. SQL failures now return 400 with the canonical error
shape plus the "redirect" context key from on_error_redirect; the
QueryWriteRejected 403 branch uses the canonical shape too. Successful
executions and the HTML flash-message flow are unchanged.

The default forbidden() hook previously rendered an HTML error page even
for .json requests. It now returns the canonical JSON error shape with
status 403 when the request path ends in .json or the request sends an
Accept: application/json or Content-Type: application/json header. HTML
requests still get the error page.

All JSON error responses now use a single format built by the new
datasette.utils.error_body() helper:
{"ok": false, "error": "...", "errors": ["..."], "status": 400}
- error is all messages joined with '; ', errors is the full list,
status always matches the HTTP status code
- The exception handler no longer emits the legacy title key in JSON
(it is still available to the HTML error template)
- The permission debug endpoints (/-/allowed, /-/rules, /-/check,
POST /-/permissions) no longer return bare {"error": ...} objects
- JSON renderer SQL errors keep their rows/truncated context keys but
now include the canonical keys as well
- _shape=object misuse (queries or tables without primary keys) now
returns HTTP 400 instead of 200 with an error body
- Method-not-allowed 405 responses use the canonical shape
Adds tests/test_error_shape.py covering all four previous shape
producers, updates affected tests, and documents the format in a new
'Error responses' section of docs/json_api.rst.
Implements section 1 of stable-api-recommendations.md.

Render omitted auto integer primary key values as muted auto text in the bulk insert preview so generated IDs are easier to understand.
Expose the auto primary key flag in insert UI metadata and cover the preview behavior in Playwright.
New create-view and drop-view actions.
Also fix a related bug in analyze_sql_tables(): SQLite's authorizer fires a spurious SQLITE_DELETE callback against the view name when a view is dropped (the same thing it does for dropped tables), which was incorrectly surfaced as a delete-row requirement on the view. Broaden the existing drop-table-delete suppression to cover dropped views too.
Closes#2819
