feat: add Kimi Code plugin (#657)

Native Kimi Code plugin: systemPromptPath puts AGENTS.md into the system prompt every turn, and the six skills double as slash commands. No hooks and no Kimi-specific runtime code. Verified with Kimi Code 2.1.1 over ACP.

+## Kimi Code
+
+In Kimi Code, run `/plugins install https://github.com/DietrichGebert/ponytail`, then `/reload` or start a new session. The plugin puts [`AGENTS.md`](AGENTS.md) into the system prompt every turn and adds the six skills, which Kimi also offers as `/ponytail`, `/ponytail-review`, `/ponytail-audit`, `/ponytail-debt`, `/ponytail-gain` and `/ponytail-help`. Level switching (`/ponytail lite`) loads the skill for that turn; there is no persistent mode flag in Kimi.
