anumati v1.1.1

• A website (GitHub Pages, https://theyashsawarkar.github.io/anumati/): the README as a home page, the
  changelog, and architecture decision records (docs/adr/), built from these files by
  scripts/build-site.py; CI checks the site is up to date.

anumati v1.1.0

• Renamed from vayu-elevate to anumati (अनुमति, "permission") and
  moved into its own repository. Everything moves with the name:
  /usr/local/bin/anumati, /usr/local/lib/anumati/,
  /var/log/anumati.log, ~/.local/state/anumati/requests.jsonl, the
  window's app id io.github.theyashsawarkar.Anumati, the MCP server name.
• install.sh (was Vayu's ai/apply.sh) installs it root-owned, keeps
  /usr/local/bin/vayu-elevate as a link so the old name still works,
  removes the old /usr/local/lib/vayu-elevate, and gains --uninstall.
• Tests for request validation, and CI.
