Phase 3: Personality types & config schema

[robinmordasiewicz]

Parent Epic

Closes part of #20334

Problem

No typed schema exists for personality definitions in config.

Acceptance Criteria

• `Personality.Info` and `Personality.Spec` zod schemas defined (string + dict format)
• `Config.Info` extended with optional `personality` field
• Schema validates both string and structured (description, system_prompt, tone, style) formats
• Tests in `test/personality/personality.test.ts` pass (TDD)

Reference

• Hermes config.py personalities
• Hermes test_personality_none.py

Files

• `packages/opencode/src/personality/index.ts` (new)
• `packages/opencode/src/config/config.ts`
• `packages/opencode/test/personality/personality.test.ts` (new, TDD first)
