Better auth type errors

[eluce2]

Fixes TypeScript build errors in @proofkit/better-auth by updating type imports and adapter option parsing to be resilient to upstream changes.

The build was failing due to several TypeScript errors in @proofkit/better-auth related to type mismatches and missing exports from the better-auth dependency. These changes address those issues by:

• Replacing direct imports of potentially volatile types (AdapterDebugLogs, BetterAuthDbSchema) with stable local definitions.
• Implementing a more robust way to extract adapter configuration from adapter.options to handle variations in the better-auth package's internal structure.
• Normalizing field types in src/migrate.ts to correctly handle array-based types from better-auth.
  This ensures the @proofkit/better-auth package builds successfully with the current better-auth dependency.

Note

Strengthens compatibility with evolving better-auth types and adapter options to resolve TS build errors.

• Replace imported BetterAuthDbSchema with local BetterAuthAuthTables and add normalizeBetterAuthFieldType to handle string/array union field types in migrate.ts
• Update adapter.ts to stop importing AdapterDebugLogs and widen debugLogs to boolean | { isRunningAdapterTests?: boolean }
• Add getFileMakerAdapterConfigFromAdapterOptions in CLI and use it to read config from adapter.options.config or adapter.options.adapterConfig.config; wire into migration flow
• Add changeset entry declaring a patch for @proofkit/better-auth

@cursor add a changeset for this update

[cursor]

Added. I’ll include a changeset for @proofkit/better-auth documenting the build/type-compatibility fix (resilient parsing of adapter options + normalized schema field typing) so it gets versioned/published correctly in this PR.
