The kilocode provider uses OAuth device flow + direct HTTPS to api.kilo.ai
and never depends on the local kilocode CLI binary at runtime. The connection
test was hard-failing with "Local CLI runtime is not installed" even when the
OAuth token itself was perfectly valid, blocking all kilocode setups on hosts
where the CLI binary was not also installed.
Removed kilocode from CLI_RUNTIME_PROVIDER_MAP and extracted the constant to
a dedicated module so unit tests can pin the contract without dragging the
full Next.js route + DB initialization into the test runtime.
CLI Tools integration (/api/cli-tools/kilo-settings, used to configure the
Kilo VSCode extension to point at OmniRoute) keeps its own runtime check
since it actually does need the CLI binary to be present.
