Subject: [PATCH] feat(02-01): create skill type definitions and constants

- SkillSourceType union with 5 source kinds (github, local_path, url, skills_sh, managed)
- TrustLevel union with 3 levels (markdown_only, assets, scripts_executables)
- FileInventoryEntry with 6 kind classifications
- SkillRecord interface matching company_skills table columns
- TOKEN_BUDGETS constant with per-adapter token caps
- RuntimeSkillEntry, ManagedSkillRef, SkillAssignment, SkillUpdateStatus interfaces
