Commit Message

Instantiate validators at definition time

Validators are now instantiated once at route definition time and frozen,
rather than per-request via ValidatorFactory. This removes repeated object
allocation from the hot path and moves option parsing, converter building,
and message formatting into initialize.

- Remove ValidatorFactory; ParamsScope#validate instantiates validators directly
- Freeze validator instances via Base.new override (super.freeze)
- Add Grape::Util::DeepFreeze to recursively freeze Hash/Array/String options
- Freeze ParamsScope at end of initialize; cache full_path as @full_path
- Promote validate_param! to protected with NotImplementedError default
- Extract validation_error!, hash_like?, option_value, scrub helpers in Base
- Add default_message_key class macro for pre-computing exception messages
- Eager-initialize all built-in validators (coerce, default, values, regexp, etc.)
- ContractScopeValidator no longer inherits Base (standalone with freeze)
- coerce_type receives only extracted coerce keys; callers skip manual deletes
- Add DeepFreeze spec; add SameAsValidator and ExceptValuesValidator specs
