feat(integrations): change Augment from flat rules to skill bundles

- Convert Augment integration from flat .augment/rules/*.md to directory-based .augment/skills/<name>/SKILL.md structure
- Align Augment format with Windsurf and OpenCode skill bundle pattern
- Copy supporting folders (scripts/, references/, templates/) to each Augment skill directory
- Update frontmatter from 'type: auto' to standard 'name' + 'description' fields
- Update README documentation for new directory-based installation path

This change is possible because Augment Code now supports skills in beta, allowing us to move from the flat rules format to full skill bundles. This gives Augment users access to the complete skill ecosystem including Python automation tools and reference documentation, not just the markdown content.
