feat: add lark-scan-report skill

[KasparChen]

Summary

Adds skills/lark-scan-report — a skill that generates structured Lark/Feishu work reports as message cards by combining task data and chat messages.

Five report types:

• morning: TOP 3 tasks (DDL today > P0 > overdue) + overnight action items
• evening: Completed tasks + tomorrow push list + conversation highlights
• quick-scan: Delta @mentions + task updates since last scan; plain text if nothing new
• full: Comprehensive snapshot across all sources
• weekly: Two output blocks — exec-facing narrative + internal task list

Implementation notes

• tasklists list returns error 1470500 — skill discovers tasklist GUIDs from tasks list response, then fetches per GUID via tasklists tasks
• Sections API returns 404 — section GUID to name mapping is hardcoded in config.yaml
• .last-scan-ts tracks last scan time to avoid re-processing messages on every run
• Output sent via messages-send --msg-type interactive --as bot

What is included

• SKILL.md — Full execution flow, API workarounds, formatting rules
• README.md — Bilingual EN/ZH: installation, triggers, required permissions with copy-paste JSON
• config.example.yaml — Clean template with no personal data
• templates/ — Five report templates (card structure + extraction logic)
