Importing the public skill module first crashes through an ESM cycle #37424

What to build

Remove the order-dependent ESM initialization cycle that makes a fresh process crash when @opencode-ai/core/skill is the first Core module imported.

The current cycle is skill.ts -> permission.ts -> session.ts -> skill.ts. Session.SkillNotFoundError eagerly reads SkillV2.ID before the skill module initializes, producing ReferenceError: Cannot access 'ID' before initialization.

This also prevents the focused aggregate config hot-reload test from running in isolation.

Acceptance criteria

• A fresh Bun process can import @opencode-ai/core/skill without preloading another Core module.
• packages/core/test/config/reload.test.ts runs in isolation.
• The error schema continues to use the canonical skill ID schema.
• A fresh-process import regression test passes deterministically.
