feat(deps): support AI SDK v5 and v6 via unified imports

Remove direct dependencies on @ai-sdk/provider and @ai-sdk/provider-utils
internal packages. Import JSONSchema7 and Tool types directly from the
main 'ai' package instead.

This change:
- Removes @ai-sdk/provider and @ai-sdk/provider-utils from devDependencies
- Updates peerDependencies to accept ai >=5.0.0 <7.0.0
- Simplifies the dependency tree for consumers

Both AI SDK v5 and v6 export the required types from the main package,
making the internal package dependencies unnecessary.
