feat(storage): gate JSON write operations on OpenCode beta, document degraded features

- Gate session-recovery writes: injectTextPart, prependThinkingPart, replaceEmptyTextParts, stripThinkingParts

- Gate context-window-recovery writes: truncateToolResult

- Add isSqliteBackend() checks with log warnings

- Create beta-degraded-features.md documentation
