fix(session-start): truthful banner — derive ALWAYS_ON, label graphify, greedy split

- ALWAYS_ON derived from settings.json:enabledPlugins (true entries)
  minus toggle-owned names — the hardcoded pair under-reported newly
  enabled plugins (pr-review-toolkit enabled yet invisible). LRN-005.
- Display 'graphify' (the CLI/skill name); graphifyy stays the pipx
  package name everywhere it IS the package.
- Overflow split = greedy width-fill: the fixed 3-name cut overflowed
  line 1 and printed an empty line 2 with 3 long names.
