```
Worker-level Docket dependency that restores the task-context snapshot.
Runs before each fastmcp-owned task, populating the snapshot ContextVar
so user code — and any task-scoped dependency like ``_CurrentContext`` —
sees a ready snapshot without touching Redis itself. All Redis I/O
goes through Docket's async client, so cluster URLs and the memory://
backend work transparently (#3897). Failures are non-fatal: the task
still runs, and sync helpers return ``None`` as they would have before
the snapshot was captured.

- Enums and constants
- Union types
## Unsupported regex patterns
Pydantic uses a Rust-based regex engine that does not support all regex
features found in real-world JSON Schemas (particularly those from AWS,
Azure, and other large OpenAPI providers). Unsupported constructs include
lookahead/lookbehind assertions (`(?!...)`, `(?<=...)`), Unicode property
escapes (`\p{Graph}`, `\p{Print}`), and very large compiled patterns.
When a `pattern` constraint cannot be compiled, `json_schema_to_type`
degrades gracefully:
1. The pattern is **dropped** from the Pydantic `StringConstraints` so
the type will not raise a `SchemaError`.
2. A `UserWarning` is emitted with the unsupported pattern.
3. The original pattern is preserved in the type metadata as
`x-unsupported-pattern` (visible via `TypeAdapter(T).json_schema()`).
4. Other constraints (`minLength`, `maxLength`) are still enforced.
