feat: add Kimi Code CLI support

Adds kimi-code to both platform-codes.yaml files so Kimi Code CLI
is available as an install target via the config-driven installer.
Skills are installed to .kimi/skills/, which is the project-level
skills directory per the official Kimi Code CLI documentation.

Closes #1630
