feat(notifications): persistent-pending model + wofi history picker

Notifications now behave like a phone: pop briefly, auto-disappear, and
remain "pending" until the user explicitly acknowledges them. The waybar
count reflects pending only; idle uses a quieter glyph.

State model:
  pending = ids in mako history/list MINUS dismissed-set
  state file: $XDG_RUNTIME_DIR/mako-dismissed (per-session id list)

Glyph change:
  idle (0 pending)     bell_outline U+F009C
  has pending          bell_ring    U+F009E
  (the previous bell_check_outline U+F11E8 "history present but nothing
   pending" branch is gone — there is no separate history concept now)

Bindings (all now go through wrappers that maintain the dismissed-set):
  Super+n          dismiss top visible + mark seen
  Super+Shift+n    dismiss all visible + mark seen
  Super+Ctrl+n     restore most recent + pop it from dismissed-set
  XF86Favorites    history picker (rewritten on wofi)

History picker (dot_config/waybar/executable_mako-history.py):
  - wofi --hide-search: arrow-only navigation, no fuzzy input
  - lines tagged [pending] / [seen] with app + summary + body
  - Enter        re-emit via notify-send (re-shows the bubble) + mark seen
  - Alt-c        copy "summary\nbody" to clipboard via wl-copy
  - Alt-d        mark seen without re-showing
  - empty history shows a sentinel, no-op on Enter

New scripts:
  executable_dismiss-visible.sh   capture id(s) then makoctl dismiss
  executable_restore-pending.sh   capture top-of-history id, restore,
                                  then drop that id from dismissed-set
  executable_mako-history.py      Python rewrite (parses makoctl text
                                  output, drives wofi)

Other:
  meta/wayland.txt                add wofi (only used by this picker)
  dot_config/wofi/style.css       minimal gruvbox style; hides input row
                                  as belt-and-suspenders even though
                                  --hide-search already does it

+"""Notification history picker.
+
+Lists mako's history annotated with pending/seen status. Default action

+Alt-c copies "summary\\nbody" to the clipboard via wl-copy.
+Alt-d marks the entry seen without re-showing.

+State file: $XDG_RUNTIME_DIR/mako-dismissed (one id per line, per-session).
