refactor(llm): add attachment-resolution infra (#485)
## Summary

Next step of the gateway refactor (after #481): a small, codec-agnostic
step for resolving file-backed attachments to inline data, shared by the
per-dialect codec extractions that follow (anthropic, openai_responses,
gemini).

Codec `encode` is sync and never touches the filesystem. Today each
adapter loads file-path `Image`/`Document`/`Audio` parts inline via
`common::load_file_as_base64` mid-translation; the codec split needs
that I/O hoisted out so encode can stay pure. `attachments::resolve`
does it: clone the request, load each file-path part (per the caller's
`AttachmentPolicy`) into inline bytes + MIME, drop the part on load
error (the long-standing contract), and leave non-file URLs and
already-inline data untouched.

- `AttachmentPolicy { images, documents, audio }` — each dialect adapter
constructs the policy it wants when it wires this in (anthropic:
images+documents; openai: images only; gemini: all three).
- `common::load_file_bytes` (raw bytes + MIME) factored out of
`load_file_as_base64`, which now delegates to it.

Splitting this out of the anthropic extraction makes the three
dialect-codec PRs independent siblings — they can go up and land in
parallel once this merges.

Added ahead of its consumers, so the module sits behind a justified
`dead_code` allow until the first dialect codec calls it (the anthropic
PR drops the allow). No behavior change.

## Testing

- `cargo nextest run -p fabro-llm` — 515 passed (including the 126 wire
snapshots; byte-identical, nothing reachable changes)
- `cargo check --workspace`
- `cargo +nightly-2026-04-14 clippy -p fabro-llm --all-targets -- -D
warnings`
- `cargo +nightly-2026-04-14 fmt --check`
