v0.4.2 — Post-audit Critical fixes + docs polish

Critical findings closed (post-Phase-4 UX audit)

• C1 — tar compaction no longer orphans Dream pairs. Transparent
  tar extraction in dream diff and dream rollback; dream history
  shows STORAGE column (dir / tar).
• C2 — backups prune no longer eats Dream restore points.
  ~/.cc-janitor/backups/dream/ partitioned off by default;
  --include-dream opts in with per-pair granularity. backups list
  groups by [settings] / [dream].
• C3 — TUI hook-logging toggle works again. ConfirmModal +
  tui_confirmed() wired in hooks_screen.action_toggle_logging
  (silently failing since 0.3.2).
• C4 — Memory TUI bindings cleaned up. Dropped unimplemented
  e / m. Implemented a (archive, reversible via undo) and f
  (duplicate-line preview toggle). Final BINDINGS = {r, a, f}.
• C5 — stats sleep-hygiene exposes contradicting pair content.
  Both JSON and text output now include subject + file list, not just
  count.

Bonus

• cc-janitor undo reverses dream rollback.
• cc-janitor config init [--force] scaffolds
  ~/.cc-janitor/config.toml with documented defaults.
• Malformed config.toml now warns to stderr instead of silently
  falling back to defaults.
• All 8 TUI tab labels routed through i18n.
• dream rollback dry-run warns about discarded post-snapshot dreams;
  success message points to cc-janitor undo.

Documentation

• README.md drops outdated "not on PyPI" warning; install block uses
  uv tool / pipx. Phase 4 section restructured.
• README.ru.md fully resynced (was still describing Phase 1 only).
• docs/cookbook.md Phase-3 recipes reformatted to Problem / Commands /
  Expected output / Next step style; sections renumbered.
• docs/CC_USAGE.md updated with new commands and the dream-partition
  guidance.

Tests

269 → 290 (+21 covering C1-C5 + bonus features). CI green on Ubuntu
