UID 995 conflicted with sshd on orion. Let NixOS auto-assign the UID
for the mcp system user. Use systemd's %U specifier for XDG_RUNTIME_DIR
instead of the hardcoded UID.

The FIDO2 crypttab options are already on the correct UUID-named device
in hardware-configuration.nix; the "crypted" name only applies to
disko-provisioned hosts (rift).

The module used explicit `config = { ... }` but also had duplicate
networking.nameservers and services.resolved.domains at the top level,
causing a NixOS module evaluation error. Merged the Tailscale nameserver
into the config block and removed the duplicates.

The master runs as an MCP-managed container, deployed via
mcp deploy mcp-master --direct. The systemd unit was a temporary
bootstrap mechanism.

Runs the MCP v2 master as a systemd service on rift. Uses
ConditionPathExists so the unit is a no-op on worker nodes
(like orion) that import mcp.nix but don't have the binary.
Starts after mcp-agent.service. Security hardened like the agent
but with ProtectHome=true (master doesn't need /run/user).

Replace fragile environment.etc.crypttab.text with
boot.initrd.luks.devices for the second SSD, matching
the pattern used for the root drive.

The agent binary is now managed by the operator (scp + install to
/srv/mcp/mcp-agent), not by the Nix flake. This allows agent upgrades
without a full NixOS rebuild.

Podman/skopeo don't use the system CA bundle for registry TLS — they
use /etc/containers/certs.d/<host:port>/ca.crt. Add the WNTRMUTE CA
there so podman push/pull to MCR works without --tls-verify=false.

Add gen-update-targets.sh to parse flake.nix and generate grouped
update targets (update-kyle, update-mc). Makefile now has install
(copy) and link (symlink) targets for rebuild-nixos. Also fix mc
flake input URLs to use /mc/ org path.

- Add mcp flake input (git+ssh://git@git.wntrmute.dev/mc/mcp.git)
- Add mcp CLI to mcpkg.nix system packages (installed on all machines)
- Update mcp.nix to use Nix-managed mcp-agent binary path instead of
hardcoded /usr/local/bin/mcp-agent

The previous commit removed the systemd service that stripped Tailscale's
~. DNS catch-all, breaking all DNS resolution — even when Tailscale is
disconnected. Restore it as fix-tailscale-dns, which restricts tailscale0
to only route ~scylla-hammerhead.ts.net queries.

The u2f udev rules set GROUP=plugdev on hidraw devices, but the
group didn't exist. Create it and add kyle to it so FIDO2 keys
are accessible without relying on logind uaccess ACLs.

Replace vendor-specific hidraw rule (3434) with libfido2 udev
package which covers all FIDO2 devices. Fixes FIDO2 key visibility
on orion.
