docs(todo): file Fn+F9 pocketbook task, close paru-vs-yay defect

Filed a [#C] task for the Fn+F9-toggles-pocketbook behavior on velox, with the investigation findings: the trigger isn't in any Hyprland bind, remapper, or pocketbook's own source, so it's parked until it resurfaces.

Also closed the paru-vs-yay research task properly: it had been left as a level-2 dated header, which is a sub-task shape, so it became DONE + CLOSED.

+On velox, pressing Fn+F9 (physical function key) toggles the pocketbook panel. It shouldn't. Raised from a home-project session 2026-06-23.
+
+Investigated 2026-06-23 and could not locate the trigger in any config. Ruled out, three ways:
+- No F9 bind (bare / $mod / keycode) in the live =hyprland.conf= (now a stow symlink), the velox host tier =conf.d/local.conf=, or the waybar config.
+- =hyprctl binds= runtime (all 90 active binds, authoritative) execs pocketbook on ONLY =SUPER+P=. No F9/XF86 path reaches it. The old touchpad toggle that used to sit on =$mod+F9= was moved to =$mod+M=, so F9 is unbound in Hyprland.
+- No input remapper (keyd/xremap/input-remapper) and no hotkey daemon (sxhkd/swhkd) running or configured; pocketbook's own source has no F9 / GlobalShortcuts / portal / dbus listener (its GTK ShortcutController binds only Esc/Ctrl-n/Ctrl-j/Ctrl-k/Del/Return). pocketbook is a single-instance Gtk.Application, so any path that re-runs =pocketbook= toggles it.
+
+Parked at Craig's call (not worth deeper investigation now). If it resurfaces, the one unfinished step is to capture what keysym Fn+F9 actually emits (=wev -f wl_keyboard:key=, press Fn+F9, read the =sym:= / =code:=) and grep for that. Most likely folds into removing pocketbook from the waybar setup — if pocketbook leaves the bar, retire this with it.

 Research done 2026-06-10, adoption decisions pending. Full report: [[file:docs/2026-06-10-modern-cli-tools-evaluation.org][docs/2026-06-10-modern-cli-tools-evaluation.org]]. Recommendation: adopt bat, dust, hyperfine, tealdeer, doggo (all in extra, all actively maintained); optional xh/jless/sd/ouch; nothing already-adopted has been superseded. Say which to install and I'll add them to archsetup + the machines.

 Research done 2026-06-10: [[file:docs/2026-06-10-paru-vs-yay-evaluation.org][docs/2026-06-10-paru-vs-yay-evaluation.org]]. The maintenance picture inverted since the task was filed: yay released v12.6.0 on 2026-06-07 with active triage, while paru has had no release in 11 months, no commit in 5, and a stable that fails to build against current libalpm (issue #1468 open 6 months). For an installer that bootstraps the AUR helper unattended, paru is the riskier choice on every axis that matters. No decision needed — the evidence closes this one; revisit only if paru's maintenance resumes.
