DingTalk Workspace CLI 1.0.20 డౌన్‌లోడ్

Documentation polish and a login regression fix. No behaviour changes outside the login MCP refresh path.
Fixed
- Login no longer reuses stale clientId from an old MCP cache (#213) — dws login now unconditionally re-fetches the MCP descriptor, so a previously cached client id can't keep producing auth errors after the server rotates it.
Docs
- dws chat message list pagination (#218, fixes #195) — clarifies that nextCursor is opaque and must be passed back as --cursor exactly; warns against parsing or reusing it as an offset.
- dws contact search examples (#209) — switched from the removed --keyword flag to the current --query.
- dws todo help text (#205) — expanded field semantics so MCP wrappers generate accurate schemas.
- chat message send-by-bot and report create help (#217, #106, #107) — --robot-code / --title / --text now carry the (必填) marker; report create --contents documents the key=field_name requirement and rewrites examples as a template detail → create two-step pipeline.
- CHANGELOG backfill for 1.0.19 (#204).
