[instructions] Sync inline skills instructions with v0.74.8

[github-actions]

Instructions Update — Synchronized with v0.74.8

Updates .github/aw/ instruction files to reflect the inline skill extraction/runtime support added in #34874 — the only commit between v0.74.8 and now.

Files Changed

• .github/aw/skills.md — Rewrote the Inline Skills section to document:
  • Block delimiter syntax ## skill: `name`
  • Allowed frontmatter: description only (other fields stripped with warning)
  • Name rules including uniqueness (duplicates = parse error)
  • Engine-specific output paths (claude/codex/gemini flat-file vs. default <name>/SKILL.md)
  • Two-phase extraction: compile-time strips from effective markdown, runtime extractor writes after {{#runtime-import}} resolves
  • Added missing frontmatter --- delimiter to the example workflow snippet
• .github/aw/github-agentic-workflows.md — Added skills.md row to the Reference Documentation table so the new inline-skill syntax is discoverable from the main entry point.

Safe-Outputs Code vs Instructions Audit

Verified .github/aw/safe-outputs.md against pkg/workflow/compiler_types.go and pkg/workflow/safe_outputs_config.go. All operations exposed by the compiler (create-issue, comment-memory, dispatch-workflow, dispatch_repository, create-code-scanning-alert, actions, scripts, jobs, etc.) are documented. No drift to fix.

Validation

• Imperative mood, minimal examples
• Updates routed to the correct sub-file (no detail moved into the main entry file)
• No content duplication introduced between files
• File sizes within target limits
• Verified accuracy against pkg/parser/inline_skill_extractor.go and docs/adr/34874-inline-skill-syntax-mirroring-inline-sub-agents.md
