The /api/agent/version endpoint was returning the git-describe version
(e.g. 6.0.0-rc.2+git.58.g53a9339.dirty) for dev builds, which is always
semantically newer than the binary's embedded version (v6.0.0-rc.1).
This caused agents to loop: check version → see "newer" → self-update →
restart → still same binary version → loop again.
The agent's guard ("skip if server reports 'dev'") only fires for the
literal string "dev". Fix: return "dev" whenever IsDevelopment is true,
which covers all git-built/dirty dev instances.
