Added

• Add read-only OpenCode SQLite session discovery and detail loading.
• Add a Pi (Earendil) session provider.

Changed

• Use structured session locators to support both file-backed and database-backed sessions.

• Show OpenCode tool results mapped from session state, with a fallback for legacy tool-result-only parts.
