chore(agentic-ci): declare pydantic as direct dep of data-designer-engine

[github-actions]

Summary

• Declare pydantic>=2.9.2,<3 as a direct dependency of data-designer-engine.
• Engine source imports pydantic in 23 files (BaseModel, Field, field_validator, model_validator, ConfigDict, ValidationError) but the package previously relied on data-designer-config to pull pydantic in transitively.
• Specifier matches the existing data-designer-config pin. The [email] extra is intentionally omitted — engine has no EmailStr / email_validator usage, so the extra stays config-only.

Why

Without this, installing data-designer-engine without data-designer-config (e.g. as a standalone dep) would fail at import time. Each package should declare what it directly imports.

Test plan

• make install-dev resolves cleanly with the added dep.
• make test-engine — 2248 tests pass.

Greptile Summary

This PR declares pydantic as an explicit direct dependency of data-designer-engine, preventing import failures when the package is installed without data-designer-config. The specifier >=2.9.2,<3 aligns exactly with the existing pin in data-designer-config, and the [email] extra is correctly omitted since the engine has no EmailStr usage.

• Adds "pydantic>=2.9.2,<3" to the data-designer-engine dependency list in alphabetical order, with no other changes.

Confidence Score: 5/5

Safe to merge — a one-line addition that correctly formalises an existing transitive dependency.

The change adds a single dependency pin that matches the version already resolved transitively via data-designer-config, with the [email] extra correctly omitted. There are no behavioural changes and no other files are touched.

No files require special attention.
