Agent display version now comes from the agent line's own source
(config.agentDisplayVersion injection + defaultAgentDisplayVersion
constant, currently A2.3.0) instead of being derived from the panel's
displayVersion. Masters resolve the agent line's latest from each
release's agent-version.txt marker (selfupdate.ResolveLatestAgentTarget,
legacy tag derivation as fallback for pre-marker releases): update
intents target the marker under the panel tag, panel-only releases
produce no intent, and the nodes page badges agent rows against
their own line via PanelUpdateInfo.displayLatestAgentVersion.
Windows agent frozen at A2.2.1: release discipline in docs/release.md
+ scripts/release-build.sh (agent assets reused verbatim when the
agent code is unchanged, marker always emitted, no Windows exe),
install-agent.ps1 pinned at V2.4.0, and the A2.2.1 protocol shapes
locked by TestAgentLegacyWindows221Contract.
Agent update tests now derive their targets from the live agent
line instead of a hardcoded A2.0.x the line has passed.
