Take tinyinference's null-tolerant sequence decoder

[senamakel]

What changed

The vendor/tinyinference gitlink, to dbf7897 — the merge of
tinyhumansai/tinyinference#4. Nothing else.

Why

Several OpenAI-compatible endpoints spell "no tool calls" as "tool_calls": null
rather than by omitting the key, and Mistral-family models do it on every
plain-text completion:

{"choices":[{"index":0,"finish_reason":"stop",
  "message":{"role":"assistant","tool_calls":null,"content":"Hi!"}}]}

#[serde(default)] covers an absent key and nothing else — a key present with
null still reaches the Vec visitor and fails the whole response with
invalid type: null, expected a sequence.

The consequence for this crate is not a degraded response, it is a role that
cannot function. Found on a Lean-specialised rung (labs-leanstral-1-5), where
every sub-agent delegation to that model failed with
serialization error: invalid type: null, expected a sequence while the model
itself was answering perfectly. Any agent placed on such a rung could not
complete a single turn.

Public API or behavior changes

None here. One behavior change inherited from the bump, pinned by a test
upstream: a body carrying "choices": null now fails with
Model("openai response contained no choices") rather than a serde error — the
provider fact a caller can act on, rather than the transport being named for a
body it read perfectly.

Validation

cargo check --workspace    ok

Upstream: cargo fmt --check ok, cargo clippy --all-targets -D warnings 0
warnings, cargo test -p tinyinference --lib 266 passed, three new tests for the
null shapes.

Tinyinference update

Layer / File(s)	Summary
Update submodule reference vendor/tinyinference	The submodule now references commit dbf7897e8752a395c376fec563c12552b19032bf.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: ⚪ Minimal · up to 41445

This localized dependency update makes OpenAI-compatible responses with null tool-call sequences decode successfully without changing the public API; no actionable merge-blocking risk remains after normal checks and review.

Poem

A rabbit checks the pointer bright
Tinyinference hops in sight
One commit leaves, one takes its place
The vendor path keeps steady pace
Ears up for code, and carrots grace
