feat(confidence-engine): stabilize user-directed investigation flow

Intentional changes in this checkpoint: - Deconstruct route: use body.targetNodeId (client identity) over raw.model-invented ID - ThreadContributionsBadge: compact per-thread contribution indicator with expandable history - Reopen continuation: resume from accumulated contributions instead of reformulating - showEvidenceLimit gate: hide evidence-limit card during active investigation paths - Evidence-limit visibility correction in rendering pipeline - Section ordering: assumptions and connections after 'Still unclear' in focused result - Prompt v0.3: preserve user-stated alternatives as separate unknowns; no count inflation - 3 durable regression tests (target identity, contribution persistence, reopen state) - evidence-limit card visibility gate test suite Temporary residue removed: - test-analysis.mjs (scratch diagnostic) - 5 diagnostic console.log blocks from reasoning-workspace.jsx

+/**
+ * Focused test suite for the second contribution persistence invariant.
+ *
+ * The flow during a focused deconstruct success is:
+ *   1. handleDeconstructSubmit (workspace) calls fetch to /api/focused-investigation/deconstruct
+ *   2. Route returns { success: true, observations[], uncertainties[], ... }
+ *   3. workspace calls onFocusedContribution({ targetNodeId, question, answer, ... })
+ *   4. parent scenario-form calls appendFocusedContribution(contrib) -> [ ...prev, contrib ]
+ *   5. useEffect watching focusedContributions triggers saveSession(...)
+ *
+ * Invariant: a SECOND successful deconstruct appends to the existing collection,
+ * not replacing it. Both contributions survive a session reload.
