* Refactor to use a common checker for development version
* Adds commit sha to development version for cobra command only
Leave dashboard unaffected
* Adjust for "v0.31.1-dev" test case
which must be considered pre-release
* Drop synthetic "dev"/"0.50.0-dev" firewall feature-gate fixtures
These test cases encoded the loose strings.Contains(v, "dev")
semantics inherited from peerSupportedFirewallFeatures, but
NetbirdVersion() never produces those values — only the literal
"development" (and now "development-<sha>[-dirty]") ever flows
through the wire. The agent owns the semantics of an ephemeral
development build, so the tests should exercise the strings we
actually emit.
Replaced with development, development-<sha> and
development-<sha>-dirty cases that match the HasPrefix("development")
predicate introduced upstream.
* Remove unexistent tests on wire format
The sha / dirty flag are added only when the CLI asks the version.
Account versions is unaffacted and can only strictly match "development"
* Adds tests for IsDevelopmentVersion
