refactor(skills): split ado-cli command reference into topic files

The ado-cli SKILL.md was a 540-line monolith. Split the Full command
reference into 7 topic-focused reference files under references/:

  projects-teams-users.md, repos.md, workitems.md, prs.md,
  pipelines.md, artifacts.md, admin.md

SKILL.md is now 284 lines: overview, decision tree, quick-start,
global options, and a reference file index with a table mapping each
area to its file. Reference files are readable via:
  ado skills read ado-cli/references/prs.md

Also cleaned up stale content:
- ado-auth: removed 4 historical bug-fix rows (v0.4.2/v0.4.3 fixes)
- ado-ci: replaced version-pinned download URLs (ado-0.4.3-*) with
  version-agnostic latest release URLs
