deps: update Python Arcjet SDK to 1.3.0

[qw-in]

Advance the FastAPI and Flask examples to the coordinated Python SDK release while retaining the seven-day uv cutoff and a first-party Arcjet exception.

[arcjet-review]

Arcjet Review — 🟢 Low Risk

Decision: Approved

Rationale: Minimal dependency bump of the first-party Arcjet SDK from 1.2.0 to 1.3.0 in two example projects (FastAPI and Flask). No source code changes, no new dependencies added, no transitive risk beyond the vendor's own release. Dependency-changes trigger fires but the change is well-scoped and low risk.

Summary of Changes

Bumps the arcjet pin from 1.2.0 to 1.3.0 in examples/fastapi/pyproject.toml and examples/flask/pyproject.toml. No other changes.

Escalation Triggers

• Dependency Changes: Both pyproject.toml files are modified to pin a newer Arcjet SDK version.

Notes

The description's references to the 'seven-day uv cutoff' and 'first-party Arcjet exception' refer to repository tooling/policy not visible in this diff; they are not contradicted by the change.
