feat(ai-judge): conversation evidence with bounded whitelist capture

- add conversation.ts: compaction-aware active-branch capture, user-text-only whitelist, 16-item and 12,000-char bounds with latest-user preservation
- bump prompt to bash-shadow-v2 with explicit-user-intent authority rules and quoted untrusted intent evidence
- capture the requesting cwd and per-ask conversation state; flip evidence-quality flags from placeholders to measured values
- record the candidate-identity change for prior cohorts in the scenario-set doc

+ * Captures the serving session's current active, compaction-aware branch —

+ * outputs, not requests); compaction summaries are excluded from item
+ * text but flagged so evidence quality reports derived-context presence.
+ *
+ * Bounds (PIEXTENSIO-3 evidence acceptance): at most 16 items and 12,000
+ * rendered characters total. The tail is preserved (latest user messages
+ * matter most), the head is preserved when it fits, and a middle marker
+ * records elision — never a silent drop. Latest-user preservation: the
+ * most recent user text is always retained even when the budget forces
