fix(generator): codegen typing fixes for #298, #299, #300

[benjamineckstein]

Summary

Resolves three critical codegen typing defects. Inline object schemas are now expanded to typed objects instead of Record<string, unknown>, array query params with bracket notation are properly typed, and path parameters derive their types from component schemas including via $ref indirection.

Changes

• Response schemas with inline object+properties produce Record<string, unknown> instead of typed interface #298: Inline object response/request schemas with properties are expanded to typed objects (was Record<string, unknown>). Referenced component schemas are imported from ./models.js.
• Array query params with bracket notation (items[]) typed as unknown and serialized as flat string #299: Bracket-notation array query params (ids[]) are typed number[]/string[] and serialized via repeated append() instead of a flat String().
• Path params typed as string instead of number when schema is integer via $ref to shared parameter component #300: Path params are typed from their schema (integer -> number), including $ref-to-component indirection. The react-query hooks generator derives path-param types from the client function (Parameters<typeof fn>[i]) to stay in sync.

Generated showcase output and snapshots were updated accordingly.

Closes

• Closes Response schemas with inline object+properties produce Record<string, unknown> instead of typed interface #298
• Closes Array query params with bracket notation (items[]) typed as unknown and serialized as flat string #299
• Closes Path params typed as string instead of number when schema is integer via $ref to shared parameter component #300
