dsh-plugin-workbuddy-checkin: Delegate WorkBuddy check-in and point claiming to Agent.

This is a plugin for DeepSeek Harness (DSH), maintained by cl2458228286-creator and published in the SkillHub "Internet Tools" category. It utilizes puppeteer-core to drive local Chrome, saves the WorkBuddy login state in a separate directory, and subsequently invokes official activity interfaces via same-origin requests. This enables the Agent to perform five types of actions in a single sentence: daily check-in, claiming growth tasks, claiming "Send Cats Travel" rewards, milestone redemption, and points lottery. The process is idempotent and requires no tokens. The plugin registers three tools: `workbuddy_checkin_status` (read-only checkup), `workbuddy_claim_credits` (claim), and `workbuddy_login` (scan code login). Installation requires two steps via the graphical interface: simply paste the repository address into the DSH plugin settings page, after which no restart is needed. Users can then instruct the Agent to open a dedicated Chrome window once to log in via scan code, ensuring long-term login-free access. It operates fully automatically by default; however, `chromePath`, `nodeExecutable`, and four environment variables can be configured for non-standard environments. The README explicitly lists security boundaries: it only accesses `workbuddy.cn` and `codebuddy.cn`, contains no telemetry or uploads, and does not simulate clicks, reverse-engineer encryption, or bypass risk control. The plugin runs with the permissions of the current DSH process; users should verify the source code and MIT license before installation. The version numbers are 1.0.0 in the README and 1.0.1 in package.json.
