Bug: /resume command shows incomplete session list

Problem:
The /resume command only displays a subset of available sessions because sessions-index.json is not being updated when sessions are
created/modified.

Evidence:

• history.jsonl contains 35 unique sessionIds for this project
• Actual .jsonl session files on disk: 28
• sessions-index.json entries: only 10
• 18 sessions are invisible to /resume

Root cause:
The session index file (~/.claude/projects//sessions-index.json) is out of sync with actual session files. New sessions are not being
added to the index.

Reproduction:

1. Work on a project over multiple sessions
2. Run /resume
3. Compare listed sessions vs actual .jsonl files in the project directory
4. Many sessions will be missing from the list

Workaround:
Resume by direct session ID: claude --resume

Suggested fix:
Either rebuild the index from .jsonl files when /resume is called, or remove the index dependency entirely.
