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

+## Slice 4 note (2026-08-17): conversation evidence changes candidate identity
+
+The judge now sends bounded conversation user-intent evidence (16 items /
+12,000 chars, latest-user preserved, compaction flagged) alongside the
+command, with the true requesting cwd in the result row's evidence-quality
+flags and prompt version bumped to bash-shadow-v2. Per PIEXTENSIO-10, an
+evidence-profile change creates a new candidate identity: rounds 1–3
+(command-only, prompt v1) remain valid **diagnostic** data for that older
+candidate and are retained, but any future cohort must be collected fresh
+under the v2 evidence profile.
