feat(core): convert MetaQuery and GraphQLQueryOptions to interfaces

[Bugrabugra]

Both types were plain type aliases, which prevented consumers from using TypeScript's declaration merging to extend MetaQuery with app-specific fields (e.g. meta.queryParams read by custom data providers). Converting them to interfaces is structurally identical and fully backward compatible, but unlocks:

declare module "@refinedev/core" {
  interface MetaQuery {
    queryParams?: { _pull?: string };
  }
}

Fixes #7527

What is the current behavior?

MetaQuery and GraphQLQueryOptions are plain type aliases. Because type aliases can't be extended via TypeScript's declaration merging, consumers have no way to add typed fields to meta (e.g. meta.queryParams, read by most custom data providers to build query strings). Every key on meta is typed as any, so typos and shape mismatches go uncaught.

What is the new behavior?

Converted both to interfaces (MetaQuery extends QueryBuilderOptions, GraphQLQueryOptions). This is structurally identical and fully backward compatible, but it unlocks declaration merging:

declare module "@refinedev/core" {
  interface MetaQuery {
    queryParams?: { _pull?: string; [key: string]: unknown };
  }
}

...giving autocompletion/type-checking for custom meta fields across every hook (useTable, useShow, useList, etc.) without wrapper hooks or per-call-site casting.

fixes #7527

Notes for reviewers

This is a type-only change with no behavioral difference, so I didn't add a new runtime test (the package has no type-level test infrastructure like tsd/expectTypeOf). Verified instead by:

• pnpm build (incl. .d.ts generation) passing with zero errors for core, hasura, strapi-v4, and ui-types (all packages that reference MetaQuery/GraphQLQueryOptions)
• Full core test suite: 122 files / 1213 tests passing
• A manual smoke test confirming declaration merging works end-to-end (extended field gets autocompletion, wrong-typed value is rejected by tsc)
