feat(shell): expand tricks.fish with system aliases, bat man pages, and done plugin

- Add system aliases: dot-navigation (.., ..., etc.), color overrides for
  grep/dir/vdir, safety wrappers (cp/mv/rm -i), archive shortcuts
  (tarnow, untar), wget resume, tb (termbin), and jctl
- Set MANPAGER/MANROFFOPT to render man pages through bat when available
- Configure franciscolourenco/done notification plugin settings
  (__done_min_cmd_duration=10s, __done_notification_urgency_level=low)
- Add psmem/psmem10 memory-monitoring helpers
- Switch PATH setup to fish_add_path (handles deduplication automatically)
- Add conf.d/done.fish (done plugin v1.19.1)
- Source tricks.fish explicitly after CachyOS base config in config.fish
- Sync README with all new functions, aliases, and integrations
