The agent already reported agentversion but the interactive tray app, which ships and updates independently, had no reported version. The agent now reads the tray exe file version and reports it as trayversion; EndpointState caches it (migration 0011) and the Fleet card surfaces it beside Agent. The tray csproj gains an explicit Version so the file version is stamped. Groundwork for per-PC version surfacing and push-update targeting.

"""Cache the interactive tray app version on the endpoint state.
|
|
|
|
Adds endpointstates.trayversion: the file version of the ShopDB endpoint tray
|
|
app, reported by the agent alongside its own agentversion. The tray and the
|
|
agent service ship and update independently (they are separate exes and can be
|
|
pushed apart), so the tray version is stored as its own field rather than
|
|
assumed equal to the agent (AGENT-CONTRACT.md 2).
|
|
|
|
Nullable so an endpoint with no tray installed, or an older agent that predates
|
|
the field, reads as "unknown" rather than an empty string.
|
|
|
|
Idempotent: the column-add checks the live schema first, so a db.create_all()
|
|
site (which built the column from the model already) and a re-run both stay
|
|
clean on strict MySQL 8.
