Fixes code-yeongyu#1021 The allowed-tools field in skill frontmatter now supports both formats: - Space-separated string: 'allowed-tools: Read Write Edit Bash' - YAML array: 'allowed-tools: [Read, Write, Edit, Bash]' - Multi-line YAML array format also works Previously, skills using YAML array format would silently fail to parse, causing them to not appear in the <available_skills> list. Changes: - Updated parseAllowedTools() in loader.ts, async-loader.ts, and merger.ts to handle both string and string[] types - Updated SkillMetadata type to accept string | string[] for allowed-tools - Added 4 test cases covering all allowed-tools formats

Skills frontmatter now supports YAML array format for the allowed-tools field, alongside space-separated lists. This fixes parsing issues that hid some skills from the available list.
