Prevent + net the unescaped-quote bug in the durable prompts/pipeline

The escape-ASCII-quote rule previously lived only in ephemeral Agent-call
strings. Bake it into the durable artifacts so the next session doesn't
re-derive it:
- SUBAGENT_PROMPT.md + ENRICHMENT_PROMPT.md: explicit rule to escape any
  ASCII " inside JSON string values (Romanian „cuvânt" is the trap).
- run_enrichment.py collect_enrichment: repair malformed parts with
  escape_stray_quotes instead of dropping them — the enrichment path had no
  repair net (bad parts were silently dropped, losing that activity's
  enrichment). Extraction already had one; now both do.
