Add missing system/user prompt-injection sinks across the OpenAI,
Anthropic, and Google GenAI JavaScript models:
- OpenAI videos.create/edit/extend/remix prompts (user)
- OpenAI beta.realtime.sessions.create instructions (system)
- Anthropic legacy completions.create prompt (user)
- Google GenAI caches.create config.systemInstruction (system)
- Google GenAI caches.create config.contents (user)
Also reclassify the OpenAI legacy completions.create prompt from
system-prompt-injection to user-prompt-injection: the legacy
/v1/completions endpoint takes a single free-form prompt with no role
separation, so it is the text-in/text-out equivalent of a user message.
Note: videos.remix takes the prompt in Argument[1] (remix(videoID, body)),
and Google GenAI caches.create nests both contents and systemInstruction
under config, so the model entries differ slightly from a naive mapping.
Add corresponding test cases with inline annotations and regenerate the
.expected files.

Fixes US spelling (recognised -> recognized) across docs, QLDoc,
change note, and test fixture comments. Clarifies the handler QLDoc
to note sync/async support. Renames the supported-frameworks entry
from "vercel" to "Vercel (@vercel/node)" to avoid implying broader
platform coverage.

This adds a framework model for Vercel serverless functions so that
CodeQL's existing JavaScript security queries can detect vulnerabilities
in handlers of the form
export default function handler(req: VercelRequest, res: VercelResponse) { ... }
Handlers are identified as the default export of a module whose first
two parameters are typed as `VercelRequest`/`VercelResponse` from
`@vercel/node`. The default-export constraint excludes private helpers
that share the same signature. Type-based detection follows the same
pattern already used by `NextReqResHandler` in `Next.qll`.
The framework model covers:
- Route handler recognition (default-exported typed handlers only)
- Request input sources: `query`, `body`, `cookies`, and `url`
(the last inherited from Node's `IncomingMessage`)
- Named header accesses like `req.headers.host` and `req.headers.referer`,
modelled as `Http::RequestHeaderAccess` so header-specific queries fire
- Response sinks: `res.send`, `res.status(...).send`, `res.redirect`
- Header definitions via `res.setHeader`
Includes a library test exercising each model predicate (including a
negative case for private helpers) and query consistency fixtures
demonstrating end-to-end detection for js/reflected-xss,
js/request-forgery, js/sql-injection, and js/command-line-injection.

Introduced a new change note detailing that `DataFlow::globalVarRef` now recognizes `document.defaultView` as an alias of `window`, enhancing the modeling of data flows involving `history` in queries.
