Haiyuan CaoandCopybara-Service 223d9a7ff5 feat: Agent Skills spec compliance — validation, aliases, scripts, and auto-injection ...

Close gaps between ADK's Agent Skills implementation and the public
Agent Skills spec (agentskills.io/specification):

- Frontmatter: add field validators for name (kebab-case, max 64),
  description (non-empty, max 1024), compatibility (max 500);
  add allowed-tools alias; add extra='allow'; add populate_by_name
- utils: extract _parse_skill_md helper; use model_validate() for
  alias support; enforce name-dir matching; add validate_skill_dir()
  and read_skill_properties()
- prompt: accept Union[Frontmatter, Skill];
- skill_toolset: add scripts/ resource loading; auto-inject system
  instruction (with inject_instruction opt-out); duplicate name check;
  _list_skills() returns Skill objects
- sample agent: remove manual instruction (auto-injected now)
