OpenCode ships declarative SQLite schema engine

This is a significant milestone for self-healing AI infrastructure, moving database management from linear history to state-based reconciliation.

• –The AST-to-Apply pipeline treats the database schema as a first-class code artifact, mirroring modern Infrastructure-as-Code principles.
• –It solves the persistent "migration hell" inherent in per-project SQLite files where environments frequently drift out of sync.
• –Integration with Kysely and tree-sitter ensures high-fidelity parsing of sqlite_master and robust, type-safe SQL generation.
• –The refined API structure—separating diff and apply operations—allows for safe validation and dry-runs before committing mutations.
• –This serves as a powerful proof-of-concept for agents building their own core systems, reducing the maintenance burden on human developers.
