/insights: facets not generated, most report sections empty

Description

Running /insights generates a report where all qualitative/narrative sections show "No data" or are completely missing. Only the purely quantitative sections populate correctly.

Root cause

The ~/.claude/usage-data/facets/ directory was never created, suggesting the faceting/analysis pipeline either did not run or failed silently. The report template falls back to "No data" when faceted data is absent.

Sections working (quantitative, computed from session logs)

• Stats row (messages, lines, files, days, msgs/day)
• Top Tools Used
• Languages
• User Response Time Distribution
• Multi-Clauding (Parallel Sessions)
