Add from_value<T: Facet> to deserialize Value into typed values

This adds the missing piece for facet-value: the ability to deserialize
a dynamic Value into any type implementing Facet.

New functionality:
- `from_value<T: Facet>(value: Value) -> Result<T>` - main entry point
- `ValueError` and `ValueErrorKind` error types for detailed errors

Supports deserializing:
- Primitives (bool, i8-i128, u8-u128, f32, f64, String)
- Options (None from null, Some from non-null)
- Structs (from objects, with field defaults support)
- Enums (unit from string, tuple/struct variants from objects)
- Collections (Vec, HashMap, BTreeMap, HashSet, BTreeSet)
- Fixed-size arrays and tuples
- Smart pointers (Box, Arc, Rc)
- Nested types of any combination above

This completes the round-trip capability: you can now go from
typed Rust values -> Value -> typed Rust values.
