fix(tui+compaction): settings audit fixes, gap-line fix, subconscious compaction

- settings: open on Categories panel; "saved" message; fix ScMaxTokens
  commit path; char-boundary-safe field editor (UTF-8 panic on paste)
- tui: drop empty interstitial gap lines (trim whitespace narration)
- compaction: teach the subconscious to compact (SUBCONSCIOUS_BODY_ORIENTATION);
  memory compact resolves per-agent-type default; subconscious leans sliding_reflect
- sliding_reflect preservation pass runs as a fresh fork of the agent being
  compacted — her persona, first person, '[Threads I carried forward]'
