fix(codegen/cli): make autoEmbedWhere/autoEmbedInput generic in embedder template

[pyramation]

Summary

The generated embedder.ts template at graphql/codegen/src/core/codegen/templates/embedder.ts currently types autoEmbedWhere and autoEmbedInput to accept Record<string, unknown> — but the CLI codegen emits call sites that pass concrete generated *Filter / *Patch types (no index signature). ts-jest is lenient enough that downstream test runs stay green, but the strict tsc pass on lerna publish fails with ~74 TS2345 errors per consumer ("… is not assignable to parameter of type 'Record<string, unknown>'").

This was already patched directly on the generated file in constructive-io/agentic-db as part of unblocking their lerna publish (agentic-db#29). Without this upstream fix, the next pnpm generate:all in any consumer that uses the embedder helpers will regenerate the narrow signatures and re-break publish.

Fix: make both helpers generic, preserving the caller's concrete type and casting to Record<string, unknown> internally for field lookup. Runtime behavior is identical.

export async function autoEmbedWhere<T extends object>(
  where: T,
  vectorFieldNames: string[],
  embedder: EmbedderFunction,
): Promise<T> { /* unchanged body, typed through T */ }

export async function autoEmbedInput<T extends object>(
  data: T,
  vectorFieldNames: string[],
  embedder: EmbedderFunction,
): Promise<T> { /* unchanged body, typed through T */ }

Review & Testing Checklist for Human

• Regenerate a consumer SDK (e.g. run pnpm generate:all in agentic-db against this branch) and confirm the regenerated embedder.ts matches the patch that landed in agentic-db PR Feat/test graphile #29.
• Confirm lerna publish's strict tsc pass succeeds on a consumer that exercises autoEmbedWhere / autoEmbedInput call sites from CLI commands with concrete *Filter / *Patch types.

Notes

• Template-only change; no runtime behavior difference and no change to EmbedderFunction or to the call-site codegen.
• The same generic signature is already live in agentic-db at sdk/cli/generated/cli/embedder.ts, so this upstream change just prevents the next regen from reverting it.
