docs: establish Ollama as the documentation engine

Route all prose generation (session logs, commit messages, Syncro
comments, client notes, code docs) through Ollama qwen3:14b by default.
Claude reviews output and owns verbatim-accuracy sections (credentials,
IPs, command outputs). GrepAI context lookups keep the Ollama service
warm, eliminating the 30-50s cold-start in normal workflow.

Updates: OLLAMA.md (documentation engine scope + warm-start note),
CLAUDE.md (Ollama section), save.md (narrative drafting), checkpoint.md
(commit message body drafting).
