feat(confidence-engine): v0.59a — correct Investigation revision provenance

Semantic revision tracking ensures every meaningful persisted Investigation change advances investigationRevision exactly once, while Report generation records (but does not advance) the current revision as generatedFromRevision for provenance integrity. Corrections: - updateFindingDisposition: add setInvestigationRevision(+1) for semantic transitions (eligible→not_relevant, restore) - updateFindingProposition: add no-op guard + setInvestigationRevision(+1) - onRestart/ContinueLaterBanner/reset button: add setInvestigationRevision(0) - onSituationGraphChange (Re-open seam): already had revision +1 in dirty impl Established behaviour preserved: - Re-open via reopenResolvedUnknown → onSituationGraphChange → revision +1 - Empty Done via handleDoneForNowPromotion → revision +1 - Report generation records generatedFromRevision, advances by 0 - Autosave passes revision but does not increment it - clearInvestigation() ownership intact Tests: targeted Vitest suite (17 tests) covering all provenance boundaries. Durable rule documented in current-handoff.md §v0.59a.
