feat: training data pipeline — knowledge entries → JSONL training pairs

Add scripts/knowledge_to_training_pairs.py which reads quality-gated
knowledge entries from knowledge/index.json and emits terse→rich
training pairs in JSONL format.

Features:
- Derives terse queries from facts via category-aware heuristics
- Configurable quality filters: min-confidence, model-filter, date range
- Output includes domain, source_confidence, source_model
- Smoke tests added in tests/test_knowledge_to_training_pairs.py

Deliverables for #199:
1. Pipeline script: scripts/knowledge_to_training_pairs.py
2. End-to-end: knowledge/index.json → training_pairs.jsonl (or custom JSONL)
3. Config: min-confidence, model-filter, after/before date filters
4. Test: 9 smoke tests covering conversion, filtering, and end-to-end run

Closes #199

+knowledge_to_training_pairs.py — Convert quality-gated knowledge entries into training pairs.
+
+Reads knowledge/index.json (or a custom JSONL of entries), applies quality filters,
+and emits terse→rich training pairs in JSONL format for model fine-tuning.

+Usage:

+        --output training_pairs.jsonl \
+        --min-confidence 0.7 \
+        --model-filter claude-sonnet,gpt-4 \
+        --after 2026-01-01
