dsh-number-format: Number Formatting Tool

The `dsh-number-format` plugin of DeepSeek Harness (DSH) aims to provide a unified number formatting solution. Maintained by uckkk, it supports thousands separators, decimal-place control, currency symbol insertion, and percentage formatting. After installation, configure the `dsh.profile.bundles` field in the profile's `package.json`. To use it, call the `format_number` tool directly, such as `format_number(value=1234567.891, currency="¥", decimals=2)`. This plugin depends on `@deepseek-ai/cordis` and `@deepseek-ai/`
