feat(sqlite): inspect offline snapshots with selective evidence (#2271)

Add offline SQLite database/WAL inspection through the shared CLI/MCP.

Use compact inventory, selected-table schema, exact ordered columns and
bounded row samples while preserving source identity and lossless values.
Retain completed Evidence through late cancellation and private-root cleanup
failures, bound concurrent inspections, and recheck journal validity after
acquisition. Reuse prepared CI runtime artifacts across supported Node lines.
