Ravi Tharuma 79ec594c1f fix(embeddings): support secure multimodal inputs (#7978)
* fix(embeddings): support secure multimodal inputs

Closes #7956

* fix(embeddings): translate multimodal inputs and harden URL/base64 bounds

Reject oversize base64 before format validation to avoid Zod stack overflows,
translate canonical items to Jina modality-keyed and Gemini embedContent
contracts, and fetch HTTPS media server-side with DNS pinning before provider
submission.

Closes #7956

* fix(embeddings): pin DNS only for embedding media fetches

Default remote-image fetch keeps the previous globalThis.fetch path so
image-generation tests and callers stay mockable. Multimodal embeddings
still opt into undici DNS pinning for URL media.

* fix(embeddings): close 2 SSRF/DoS gaps in secure multimodal input (#7978)

Closes two gaps in the multimodal embedding input hardening from #7956:

1. `createPinnedFetch()` (the connection-pinning mechanism that closes the
   DNS-rebinding TOCTOU window, GHSA-cmhj-wh2f-9cgx) had zero test coverage
   anywhere in the repo. Writing that test surfaced a real regression: its
   custom `connect.lookup` only implemented the single-address callback
   form `(err, address, family)`. Node's autoSelectFamily/Happy Eyeballs
   (on by default since Node 18) calls `lookup` with `{ all: true }` and
   requires the array form `(err, addresses[])` — the mismatch threw
   `ERR_INVALID_IP_ADDRESS` on every real pinned fetch, silently breaking
   all URL-sourced multimodal embedding requests in production. Fixed by
   branching on `options.all`.

2. The documented "16 MiB decoded per request" cap was enforced by the Zod
   schema only for base64-sourced items; URL-sourced items were excluded,
   and all up-to-32 items were fetched concurrently via `Promise.all` —
   allowing ~256 MiB in memory at once (16x the documented bound). Fixed by
   resolving items sequentially with a running byte budget shared across
   base64 and fetched-URL sources, rejecting once the aggregate is
   exhausted instead of after over-fetching.

Adds tests/unit/remote-image-fetch-pin-dns-connection.test.ts (real
loopback-server pinning tests) and a new aggregate-cap test in
tests/unit/embeddings-multimodal-7956.test.ts; both were verified to fail
against the pre-fix code before the corresponding fix was applied.
