Describe your changes

The only relevant breaking change in mistralai v2 was the removal of top level exports. See https://github.com/mistralai/client-python/blob/main/MIGRATION.md. Parts of the code and documentation where still on v0, those have now also been updated.

I need this 🙏🏻

actually isn't backwards compatible, it didn't install the older version when I was testing it

## Summary

- accumulate declared, nested, and unknown numeric OpenAI/Anthropic
usage fields across retries while preserving non-numeric metadata
- add corrective feedback when a Responses API retry receives no tool
call
- preserve raw iterable type hints through sync and async v2
parallel-tool wrappers
- strengthen API-key-free coverage for current and future SDK usage
counters

## Consolidated and superseded items

- closes #2493
- consolidates contributor work from #2498, #2500, and #2501 with
original commit authorship preserved
- supersedes #2497 because it drops unknown `model_extra` counters
- supersedes #2499 because its hand-maintained provider field lists
would drift as SDKs evolve

## Validation

- focused changed-surface suite: `110 passed`
- broad offline v2/coverage suite: `2368 passed, 91 skipped, 73
deselected`
- Ruff check and format check: passed
- scoped `ty check`: passed
- `uv lock --check`: passed
- pre-commit hooks and `git diff --check`: passed

The 73 deselected tests require live provider credentials. An unfiltered
local run confirmed its 22 failures were provider network connections in
the restricted environment; GitHub provider jobs remain the
authoritative validation for those paths.

## Intentionally skipped

- provider additions or expansions: #2436, #2435, #2423, #2409, #2384,
#2322, #2306, #2298, #2283, #2168, #2086; issues #2408, #2383, #2365,
#2260, #2084, #2076
- broad architecture, product, security, or streaming decisions: #2394,
#2392, #2357, #2356, #2355, #2351, #2321, #2307, #2287, #2263; issues
#2479, #2403, #2393, #2391, #2316, #2272, #2056
- dependency batch: #2433
- nontrivial examples and editorial/resource additions: #2468, #2405,
#2401, #2354, #2346, #2311, #2305; issue #2404

These remain open because they need dedicated product, architecture,
provider, security, dependency, or editorial review and are not required
for the `1.15.5` patch release.

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> Changes retry usage totals and reask message content on failure paths;
scope is limited and heavily covered by tests, with no auth or
data-store changes.
> 
> **Overview**
> Bundles three v2 retry and wrapper fixes for a patch release.
> 
> **Retry usage accounting** replaces hand-maintained token field sums
with generic `_accumulate_models` on Pydantic usage objects. Numeric
fields (including nested models and `model_extra` counters) add across
retries; booleans and other non-numeric metadata are not treated as
billable. OpenAI and Anthropic paths share this logic.
> 
> **OpenAI Responses reask** appends a user correction when
`RESPONSES_TOOLS` validation fails but the output has no tool calls
(e.g. reasoning-only), so retries include feedback instead of repeating
the same request.
> 
> **Parallel tools** in `patch_v2` skips `prepare_response_model` and
does not replace `response_model` with the handler’s prepared wrapper
for parallel modes, keeping raw `Iterable[...]` hints so schemas and
parsed results include every member type.
