Builds on #2573.

Incremental diff for this part.

What changed

Add physical session snapshots and source-readiness counts inside a caller-owned read-only transaction. Include retained and trashed rows, complete transcripts, tool results, usage and findings without served-view limits.

Why

Cutover checks need the complete stored history, including records the dashboard does not show. Public list and transcript readers cannot provide that evidence.

Usage

No usage change. This supplies the physical reads used by the parity command later in the series.

Refs #1352.

roborev: Combined Review (5aa7bac)

Verdict: Changes require fixes for 2 findings.

Medium

• internal/rawparity/normalize.go:50: Parity snapshots omit session_plan_usage, so Codex Cloud sessions with matching transcripts and usage_events can produce identical digests despite missing or different credits, plan percentages, coverage, or CountedUnder ownership. Cutover comparison can therefore miss accounting loss.

  Fix: Include session_plan_usage in Snapshot, load it within the same transaction, and compare its accounting fields with timestamp normalization and CountedUnder relationship mapping. Add coverage for differing and missing plan usage rows.

• internal/rawparity/normalize_test.go:225: TestFrictionPhysicalIdentityFormatting duplicates TestFrictionIdentityMinimalCounterexample at internal/rawparity/normalize_test.go:269. Both detect friction titles or fingerprints incorrectly participating in parity; the generated suffix exercises no additional normalization behavior.

  Fix: Delete TestFrictionPhysicalIdentityFormatting and retain TestFrictionIdentityMinimalCounterexample, which also runs when Hegel tests are skipped.
