feat(provider): add CLAUDE_CODE_AUTO_COMPACT_WINDOW for Kimi For Coding preset (#4401)

Set the default Claude Code auto-compact window to 262144 for the
Kimi For Coding provider preset, matching the official Kimi docs:
https://www.kimi.com/code/docs/en/third-party-tools/other-coding-agents.html

Use templateValues so users can customize the value (e.g. for future
models or performance tuning) while keeping 262144 as the default.
