docs: add agent host support matrix

[hehanlin1996]

Summary

Adds a one-page Agent host support matrix and Calendar read/write recipe to README.md and README.zh.md for larksuiteGH-795 / C-20260516-04, clarifying that lark-cli is a local CLI callable from shell-capable hosts while OpenClaw / Hermes / Lark Channel only add config bind credential bootstrapping.

Changes

• Add an Agent host matrix covering Claude Code, Cursor, Gemini CLI, OpenClaw, Hermes, Lark Channel, OpenCode, QwenPaw, and plain terminal/scripts.
• Document credential paths and recommended integration choices (CLI vs Skill vs MCP) without promising unsupported automatic injection.
• Add Calendar recipe paths for hosted bind and manual config flows using lark-cli auth login --domain calendar, calendar +agenda, and calendar +create.
• Add Quick Start links so OpenClaw / Hermes / Lark Channel users find config bind before creating a separate app.

Test Plan

• Pre-change grep check confirmed README.md / README.zh.md lacked OpenCode / QwenPaw / agent host matrix coverage.
• Post-change grep checks passed for OpenCode, QwenPaw, config bind, and auth login --domain calendar in both README.md and README.zh.md.
• git diff --check
• Review diff for sensitive output: only placeholders/env var names such as <APP_SECRET> and FEISHU_APP_SECRET, no concrete secrets/tokens.
• Checked for dedicated Markdown lint/format scripts; none found (package.json only defines postinstall, and no markdownlint/prettier config was found).
• Unit tests not run (docs-only README change).
• Live CLI Calendar verification not run (would require real user/app credentials).
