FastAPI fixes blocking frontend fallback checks

The day's one behavioral change is FastAPI's fix for blocking filesystem checks in the static frontend fallback, with the rest of the wire landing on formatting, translations, and Pydantic housekeeping.
π Fix blocking frontend fallback file checks (#16503) fastapi/fastapi
Serving a static frontend now uses non-blocking fallback file checks instead of synchronous ones, so requests that miss a built asset no longer stall on disk I/O. If you mount a SPA behind FastAPI, this is the change worth taking.
π¨ Update Python format in Markdown with Ruff fastapi/fastapi
Python snippets embedded in the Markdown docs are now formatted by Ruff, which keeps documented examples consistent with the codebase, though not with how Ruff would format your own project. tiangolo's summary notes the change was made with Codex using gpt-6-astra and manually reviewed.
Add pre-commit hook to prevent invisible Unicode characters pydantic/pydantic
A pre-commit hook now rejects invisible Unicode characters, landing after 30 no-break spaces (U+00A0) across five files and one word joiner (U+2060) were removed. The affected spots were comment and text only, including the U+00A0 inside the actions/checkout pin comments in ci.yml and the BaseModel.__eq__ comment in pydantic/main.py.
Bump speedate to v0.18.0 pydantic/pydantic
The speedate dependency moves to v0.18.0, resolving the issue Viicos opened for it. Tests that exercise datetime parsing through speedate are the ones to watch on the next Pydantic build.
π Update translations for ja (update-outdated) (#16499) fastapi/fastapi
by pr-submit[bot]
The long tail is maintenance: the Japanese translations were refreshed from the outdated set, release notes were regenerated in FastAPI and SQLModel, and a mangled comment in test_pickle.py was corrected. No API changes in any of them.
