Keys containing # are now pre-quoted in all cluster output (similarity
scores, hub analysis, node headers) so the agent copies them correctly
into bash commands. Prompt strengthened with CRITICAL warning about #
being a shell comment character.
Journal entries included in clusters but identified by node_type
(EpisodicSession) rather than key prefix, and tagged [JOURNAL — no
delete] in the output. Prompt rule 3b tells agent to LINK/REFINE
journals but never DELETE them. Digest nodes (daily/weekly/monthly)
still excluded entirely from clusters.
