feat(install): add Kimi Code CLI install target (kimi-project adapter) (#2441)

Rebuild of #2154 on current main, following the hermes/openclaw (#2433)
adapter recipe: 10-line kimi-project adapter (project kind, ./.kimi root),
registry + helpers ownership, SUPPORTED_INSTALL_TARGETS + legacy-compat
modules, kimi target on the 5 shared modules + .kimi in platform-configs
paths, both schema enums, npm files allowlist, help text, README stub.

Credit to @MoYiC6 for the original adapter design in #2154.
