* feat(nixpak): support FIDO2 hotplug via udev-maintained node directory
Replace launch-time hidraw discovery with host udev rules that hard-link
FIDO-tagged hidraw nodes into /dev/fido-hidraw and remove them on unplug.
The sandbox dev-binds that directory and gets static /dev/hidrawN symlinks
into it, so keys plugged in after launch work and no stale node survives a
reused hidraw minor.
Narrow the extra mounts from whole /sys and /run/udev to /sys/class/hidraw,
/run/udev/data and /run/udev/control; the policy suite now forbids the
broad mounts and checks the wrapper and bind follow the fido2 option.

* refactor(nixpak): rewrite FIDO2 bwrap wrapper in Python
The bash argument loop was hard to follow. Python inserts the /dev/hidrawN
symlinks before "--" with a single list splice, and the header now explains
the whole host-udev -> bind -> symlink chain step by step.

* docs(canokey): document phone-only management policy
PCs only use the CanoKey; CanoKey Console management stays in the phone
app and the Admin PIN is never typed on a PC. Record what the config
enforces (sandboxed browsers get no raw USB/CCID, no vendor WebUSB udev
rule) and what it does not (uaccess on the raw USB node, PC/SC access to
the Admin applet, CTAP management from browsers).

* docs(canokey): separate management from use, link CanoKey docs

* fix(nixpak): create /dev/fido-hidraw from the udev rule
NixOS applies /dev tmpfiles entries only at boot; switch-to-configuration
runs systemd-tmpfiles-resetup with --exclude-prefix=/dev. After a switch
without reboot the directory was missing and every `ln` failed with exit
code 1, so no browser saw the key. The add rule now runs `mkdir -p` first.
Also fix the documented trigger command: `udevadm trigger` defaults to
`change`, which the add-only rule ignores.

* refactor(nixpak): keep tmpfiles as the only creator of /dev/fido-hidraw
The /dev tmpfiles units run before systemd-udevd on every boot, so the
directory always exists before coldplug. The mkdir in the udev rule only
covered the first switch without reboot and duplicated the tmpfiles rule;
drop it and document the one-time `systemd-tmpfiles --prefix` command.

* docs(nixpak): record FIDO2 hardware validation in Firefox and Chrome
After a reboot on ai with the CanoKey present at boot, udev linked only
the FIDO interface and WebAuthn works in Firefox and Chrome. Chromium and
plugging the key in after launch remain pending.

* refactor(nixpak): unify desktop app sandboxes
Move common GUI, portal, and network policy into reusable modules and migrate browsers plus Zoom/WeChat/QQ/Telegram to the same boundary.
