Make invoke and reflect unqualified

[mingxwa]

Existing pro::proxy_invoke and pro::proxy_reflect are not necessarily defined as global functions. Similar to swap, they can be defined as friend functions to scope their usage. When authoring a dispatch or reflector type, users no longer need to add qualifiers to invoke or reflect after this change.

Changes

• Added friend functions invoke and reflect to pro::proxy and pro::proxy_indirect_accessor, respectively. Their semantics align with the existing pro::proxy_invoke and pro::proxy_reflect.
• Marked pro::proxy_invoke and pro::proxy_reflect as deprecated.
• Updated unit tests.
• Spec and paper will be updated separately.

Pull request overview

This PR enables ADL-based, unqualified invoke / reflect usage for pro::proxy and pro::proxy_indirect_accessor, aligning the API with the “unqualified swap” style and allowing dispatch/reflector authoring without pro:: qualifiers.

Changes:

• Added ADL-discoverable friend function templates invoke and reflect to proxy / proxy_indirect_accessor.
• Marked pro::proxy_invoke and pro::proxy_reflect overloads as deprecated and updated internal call sites.
• Updated unit tests and accessor/formatter helpers to use unqualified invoke / reflect.
