feat(integration): update Kimi integration for Kimi Code CLI

[meymchen]

Summary

Updates the built-in Kimi integration to align with the new Kimi Code CLI layout from Moonshot AI.

Relates to #1532.

Changes

• Skills directory moved from .kimi/skills/ to .kimi-code/skills/
• Context file moved from KIMI.md to AGENTS.md
• --migrate-legacy now also migrates:
  • old .kimi/skills/ installs to .kimi-code/skills/
  • dotted skill directory names (speckit.xxx) to hyphenated (speckit-xxx)
  • user content from KIMI.md to AGENTS.md
• teardown() removes leftover Speckit-generated .kimi/skills/speckit-* directories
• multi_install_safe set to False because Kimi now shares AGENTS.md with Codex
• Devcontainer installer switched from pipx install kimi-cli to npm install -g @moonshot-ai/kimi-code@latest
• Updated docs/reference/integrations.md, CHANGELOG.md, and tests

Testing

• uv run pytest tests/integrations/test_integration_kimi.py — 43 passed
• uv run pytest tests/integrations/ — 2218 passed
• uv run pytest tests/ -k kimi — 57 passed

Please address Copilot feedback

@mnriem All Copilot feedback has been addressed in the latest commit (a5dc347).

Changes made:

• Fixed Kimi skill invocation to use /skill:speckit-<stem> so it matches Kimi Code CLI's native slash command format.
• Hardened --migrate-legacy to skip symlinked .kimi/skills directories and avoid moving content from outside the project.
• Updated teardown legacy cleanup to skip symlinks and non-directory entries before removal.
• Removed kimi from the multi-install-safe integrations table to align with multi_install_safe = False.

I also resolved the Copilot review threads. Let me know if anything else needs adjustment.
