Add descriptive, user-friendly aliases for the existing API routes to
improve gitops-agent API discoverability:
GET /api/baseline → /api/base
GET /api/versions → /api/ver
GET /api/runtime-status → /api/run
GET /api/patches → /api/patch
POST /api/create-patch → /api/patch
GET /api/branches → /api/branch
POST /api/create-branch → /api/branch
POST /api/commit-file → /api/file
POST /api/create-tag → /api/tag
All aliases wire through the same handler functions, tested live.
