v0.2.1

Release 0.2.1: drop self-praise from the README intro (#3)

"a thin, honest layer" -> "a thin layer", and the trailing "instead of
pretending otherwise" goes too. The sentence already shows the behaviour
without the project grading itself.

Version bumped so the PyPI project page, which renders this README, picks
the change up — it only refreshes on release.

v0.2.0

Guided setup, self-renewing sign-in, and one-line install (#2)

Setup was twelve manual steps and a token that died every 12 hours. Now
`mcp-webexcalling setup` guides users through creating their own Webex app,
runs the browser sign-in, and stores credentials the server refreshes
itself. Adds `doctor`, `print-config`, and `logout`, a credential store
with cross-process-safe refresh, PyPI release via trusted publishing, and a
double-click bundle for Claude Desktop.

Also fixes a genuinely incomplete scope table (missing voicemail and
recording scopes, ~7 tools affected) and a concurrent-refresh bug that
burned rotated tokens. Tests 265 -> 335, now green on Linux, macOS, and
Windows.
