"""Single source of truth for app + CLI compat versions.

`APP_VERSION` is read from package metadata so it tracks `pyproject.toml`
without a manual literal to keep in sync.

`MIN_COMPAT_CLI_VERSION` is the oldest CLI version the server still accepts
on `/api/*`. Bumped manually when shipping a wire-protocol break. Day-one
value of "0.0.0" means no enforcement — set the floor the first time a
deliberate break ships.
