v0.6.3

Changed

• augent install: --for renamed to --to with short -t for target platforms (e.g. augent install ./bundle -t cursor).
• Skill transformations (leaf as {name}, nested content under skill) now apply to all skill-supporting platforms; installs as .platform/skills/{name}/SKILL.md and .platform/skills/{name}/**/*.

Fixed

• Nested skills (e.g. skills/platform-name/skill-name/) are now installed as the leaf skill only: .platform/skills/skill-name/ with SKILL.md and any nested content (e.g. scripts/), not as intermediate path segments like platform-name.
• Workspace root resources are now discovered during install, preventing "Nothing to install" when only local root resources exist and ensuring the workspace bundle is correctly identified.
