/insights reports wildly inflated session counts (10k+ instead of actual ~450)

Description

The /insights command generates fabricated aggregate statistics that don't match actual usage data.

Observed behavior

• /insights reports 10,412 sessions, ~98k messages
• Actual data in stats-cache.json: 451 sessions, 190k messages
• Only ~1000 .jsonl files exist in .claude/projects/
• Clearing all cached data (rm -rf ~/.claude/usage-data/ ~/.claude/stats-cache.json) and regenerating produces the same wrong numbers
• After fresh regeneration, stats-cache.json isn't even created, but report still shows 10k+ sessions

Expected behavior

Session counts should match actual session files or stats-cache.json data.

Steps to reproduce

1. Run /insights
2. Compare reported session count to:

• cat ~/.claude/stats-cache.json | jq '.totalSessions'
• find ~/.claude/projects -name "*.jsonl" | wc -l

1. Numbers don't match (off by ~20x in my case)

Additional bugs found

• /bug and /feedback commands cancel when user starts typing, making it impossible to report issues from within Claude Code
