v0.1.0

• First public version, under the name Virtual Key Mapper: the command is vkm, the
  package virtual-key-mapper, the repository file .vkm and the environment variables
  VKM_*. The VS Code extensions are cbs-consulting.vkm (Copilot Chat) and
  cbs-consulting.vkm-local (local sign-in for dev containers, SSH and WSL).
• Licensed under the Apache License 2.0.
• Published on PyPI (virtual-key-mapper) by a release workflow with one shared version; the
  VS Code extensions (cbs-consulting.vkm, cbs-consulting.vkm-local) are attached to each
  GitHub release and uploaded to the Visual Studio Marketplace by hand.
• Labels: requests carry key/value labels such as
  customer = "acme" and project = "webshop", defined in the central rules document
  (version "2.0") or the profile, with required labels, allowed values and per-label
  sources. Each label is resolved on its own from --label KEY=VALUE, VKM_LABEL_<KEY>,
  vkm repo bind --label, a .vkm [labels] table or a central rule. Gateway adapters
  declare outputs; LiteLLM sends x-litellm-tags (default KEY:VALUE per label,
  overridable with ${KEY} formats) and spend-log metadata with all labels and their
  sources. New vkm labels list|values; profile add/update --label/--output;
  "Assign labels" and a status bar with all label values in VS Code. See
  docs/labels.md.
