The agent (serverkit-agent bbaf4e2) now sends install_dir and
config_dir in system_info. Panel side:
- servers.agent_install_dir + agent_config_dir columns (migration 047,
idempotent guard like its siblings) with the same coalesce contract
as the other system_info fields — a transient payload gap never
wipes a stored value
- exposed in Server.to_dict and /servers/available; TargetPicker
passes them on the agent target
- the File Manager rail prefers the reported config dir over the
installer convention (backslash-normalized for Windows agents;
agent-logs link derives <config_dir>/logs)
- proving test: full system_info -> DB -> available round trip +
coalesce survival
