deps: lockfile refresh (fastapi 0.141.1 and transitives) (#102)

## Summary

Lockfile refresh from the workspace-wide maintenance sweep. Ten packages
moved, all transitive or dev tooling, the most notable being `fastapi`
0.140.0 to 0.141.1. No source changes and no direct-dependency range
edits.

## Type of change

- [ ] Bug fix (no breaking change)
- [ ] New feature (no breaking change)
- [ ] Breaking change (existing callers must update)
- [x] Docs, tests, or internal maintenance only

## Public API

None. `fastapi` is a peer the middleware integrates against rather than
something re-exported, and its declared range is unchanged, so an
installing consumer resolves exactly as before. No exported type,
signature, or wire format changes.

## Test plan

Ran the repo's full Python gate set with exit codes read directly: `ruff
check` clean, `ruff format --check` clean at 215 files, `ty check`
clean, `pytest` 1841 passed with 4 skipped, and `vulture
--min-confidence 80` clean over the package. Every sync used
`--all-extras --all-groups` rather than a bare `uv sync`, which would
resolve base deps only and quietly strip the venv's extras and
dependency groups, breaking test collection.

## Checklist

- [x] Tests cover the new behavior, and the suite passes locally
- [x] Lint, format, and type checks pass
- [x] Docs and README examples updated if the public surface changed
- [x] No secrets, credentials, or personal data in the diff or the tests
