Pi Usage v0.2.0

What's new

• Add local usage counts for every Skill discovered by Pi through /usage skills.
• Count explicit /skill:name commands and successful Skill entry-file loads once per agent run.
• Show installed Skills with zero uses and store only the Skill name and timestamp locally.
• Keep /usage as the only registered command and remove the /quota alias.
• Rewrite the English and Chinese documentation and add Pi terminal and pi-web screenshots.

Reliability and security

• Tighten provider-domain validation and reject lookalike hostnames.
• Prevent unknown models from borrowing unrelated proxy quota pools.
• Improve configuration validation, cancellation handling, and provider error states.
• Remove unused configuration, matching, metric, and session-statistics code.
