IB-WP-0016-T04: trading-literature profile

Ship a specialized profile for trading memoirs and market-structure
texts. The profile names eight entity categories (trader, market,
strategy, error, psychological_pattern, institution, instrument,
evidence_bearing_claim), five relation types (cause_effect,
lesson_evidence, risk_mitigation, actor_venue, strategy_outcome), and
four evaluation criteria (groundedness, lesson_clarity,
historical_context, overgeneralization_risk). Each is reflected in the
prompts and contracts so the LLM is steered toward operator-level
findings rather than biographical detail or moralising.

The generic profile remains the default. A 2-chapter Lefevre smoke run
with --profile trading-literature completes end-to-end with viable
metrics; 93 tests pass.

+### Profiles
+
+Two profiles ship today:
+
+- `general-knowledge` — durable concepts, claims, methods, people,

+- `trading-literature` — trading memoirs and market-structure texts;
+  tunes entity categories (`trader`, `market`, `strategy`, `error`,
+  `psychological_pattern`, `institution`, `instrument`,
+  `evidence_bearing_claim`), relation types (`cause_effect`,
+  `lesson_evidence`, `risk_mitigation`, `actor_venue`,

+  `lesson_clarity`, `historical_context`, `overgeneralization_risk`)
+
+Select via `--profile trading-literature` on `generate init` or
+`generate from-source`. The generic profile remains the default.
