Adds the two missing cases that left lib/kernel/src/cli_install.dart:74
(default-environment constructor branch) and the builtin extension's
stale-GUI activation warning uncovered.

A command-palette / `clide` CLI verb (`clide.installCli`) copies the
bundled C client into ~/.local/bin, VS Code "Install code command" style,
so a user who runs the app without `make install` can still reach the CLI
from a shell. On launch the app detects when `clide` is missing from PATH
or resolves to a stale symlink into the Flutter GUI bundle (the dogfood
footgun: a bare `clide` launched a second app instead of querying the
socket) and notifies with a pointer to the command. `make build` now ships
the C client inside the app bundle so the affordance can self-install from
it; `make run` points it at the dev-tree client via CLIDE_CLI_BIN.
Detection and the copy live in the Flutter-free CliInstaller
(kernel/src/cli_install.dart) so they run under unit tests without a real
install.
Closes epic T-209 (ship the clide CLI on PATH).
